AI is coming for manufacturing, but I'm not interested in another piece of software that promises to replace machinists with the push of a button. I want technology that actually understands what happens on the shop floor and helps good people get more done.
That's why I was excited to sit down with David Priev from Limitless Labs during IMTS 2026. His team is building an AI-powered CAM programming assistant that works alongside machinists, helping them program parts faster, troubleshoot problems, and cut through the tedious work that slows down production.
We get into how Limitless Labs is teaching AI to understand the physics of machining, why the next generation of manufacturing software needs domain experts, and what happens when you connect programming, machine data, and inspection results. We also tackle the questions every shop owner should be asking about AI, including ITAR compliance, data privacy, and whether your programs are being used to train someone else's model.
For me, the opportunity isn't replacing our most experienced people. It's giving them better tools, bringing new talent up to speed faster, and improving the one thing that ultimately drives profitability: throughput.

How to Connect with David Priev
I used to think core values were nonsense. White collar guys in stuffed shirts telling each other how great their culture is, and then you pull up their Glassdoor page and the place is a hellhole. So I skipped that part for fifteen years. I was dead wrong, and I'm fine saying it. That's where the growth is.
We hung a QR code on the conference room wall and asked every single person here, not just the leadership team, to name three values they admire in a coworker. The words that came back got dumped into ChatGPT and came out as GRIT 3D. Growth, respect, integrity, teamwork, and then dedication, dependability, and detail in place of dark, dirty, and dangerous. Grit is the whole company. It felt like it was meant to be.
Then it got uncomfortable. Cutting 28% of the company. Finding out that when somebody lives your values and still can't produce, that one is on me and not on them. Fifteen years in, I finally feel like a president at this company instead of an employee, and I owe it to a book.

Paul Van Metre's book isn't a general business book with a machining chapter bolted onto it. It's built for this industry, and one sentence in it has been digging in my ribs for three weeks: "If precision matters on the shop floor, it has to matter in the business too."
Reading it back made me realize something that I didn't want to admit. What got me here isn't going to take me there.
This one isn't comfortable. It's me admitting I'm not as good at this as I thought I was, and then doing something about it. Stick around for part 2.
What's Covered in this EpisodeIt's been a rough couple of months in the shop. This isn't a blame session, it's a post mortem. Two things went wrong at the same time. One of them was on us. One of them wasn't. Both are worth understanding, because I'd bet at least one of them is sitting inside your company right now, just waiting.
The first one was an ownership gap. A handful of staffing decisions that each made sense on their own stacked up and left a hole nobody was standing in, and a daily quality check quietly stopped happening. We knew what needed to be done. We knew how to do it. We never said how often, or who owned it. That's the whole failure.
The second one wasn't about how we made the part at all. We've got parts that pass every spec on the print, the customer agrees they pass, and the customer still can't use them. That's the conversation nobody wants to have out loud, so I'm having it here. I walk through both failures, what they cost us, and the three changes we made so neither one can happen the same way twice.
What's Covered in this EpisodeTom Brown came back for round two, and this time we tackled the question that could change everything: Should he buy a machine shop now, or go work in one first?
He has his eye on a highly certified, 40-person shop serving prime customers, but buying it means taking on serious financial and operational risk. We break down what actually matters before signing: quality systems, tribal knowledge, employee retention, training, customer health, and whether the business can survive losing key people.
I also challenged Tom on his lack of technical experience and shared a cautionary story about a shop that unraveled after one critical employee left.
I wasn't trying to talk him out of buying a shop. I wanted to see if he could be talked out of it.
He didn't budge. That's why I think he's got a shot.
What's Covered in this EpisodeEverybody wants to own a machine shop until they find out what it actually costs them. This time I sat down with Tom Brown, a guy who just walked out of Harvard with an MBA and seven years in the Marine Corps behind him, and he wants to buy a shop. Good for him. But I gave him the version nobody else will.
You might work harder than anyone you've ever met for less money than you've ever made in your life. That's not me being negative. That's the truth about this business, and it's a truth just about every owner I know has lived through.
We got into the whole thing. SBA 7A loans, seller financing, and why so many shops sit at break even on paper because they've quietly turned into lifestyle businesses. How a bank reads the books. What to check before you sign: how old the equipment is, how stable the customer list is, and how old the people on the floor are.
Because here's the part that matters most. Owning a shop is like running a baseball team where every day is the playoffs. There's no triple-A farm club feeding you talent. Interview a hundred people and maybe one is a real class 3 machinist. The silver tsunami is real, a whole generation got pushed away from the trades, and if you lose your people you don't just lose the shop, you go bankrupt.
So we talked about the real path in. Get a job at a shop first. Find a mentor. Maybe partner with somebody who already knows how to cut metal. Write the business plan, because you haven't started anything until you have. And understand cashflow like you know yourself, because payroll doesn't care about your bad month. If you've ever thought about owning a shop, start here.
What's Covered in this EpisodeEverybody in this industry is getting sold the same scary story right now: AI is coming for your shop, and if you're small, you're finished. Chris Stevens, the MFG coach, and I think that's backwards.
The little guys, the owner operators and the shops under 30 people, might be holding the strongest hand in the whole game. They're fast. They're nimble. They can move on this stuff over a weekend while the big primes are still stuck in a committee meeting and an Excel spreadsheet.
We also get into the trap, because it's real. It's way too easy to burn six months building some AI tool to solve a 90 second problem. Feels like progress. Zero return. If you own the place, every hour you spend has to point back at one thing, and that's cash.
And no, AI isn't taking your machinists' jobs. What it's actually doing is ripping out the admin that drags your best people off the floor. Clean data still wins. Relationships still win. DFM still wins. And the shops that treat their people like the IP they are are the ones that come out ahead.
This one runs the whole gauntlet: the 50 billion dollar fear machine, why the best shops in the country stay invisible while the hellholes go viral, the dying apprenticeship, and whether these AI brains eventually end up driving robots on your floor. Let's get into it.
What's Covered in this EpisodeEverybody wants the highlight reel. The 13,000 square foot shop, the wall of CNC machines, the certifications on the wall. Nobody wants to hear about the two toilets, the seven parking spots for 26 people, or the rigger who sliced a neighbor's Tahoe clean in half. That's exactly the part we're telling you today.
This is the first episode Lee and I have done together, so we figured we'd start where it all started. We met on match.com back in 2010. A few months in, she told me to go get a job. I did, hated it, and then she dared me to start my own shop. That dare turned into Marzilli Machine.
We walk through the stuff the how-to-start-a-business books skip right over. Writing a real business plan with the SBA. Convincing a bank to bet on you. Zoning, remediation, and finding a building nobody could ever find. Starting with one 1997 Haas and a surface grinder in a garage wedged between apartment buildings in Fall River.
We also get into the grind nobody brags about. Eighty to a hundred hour weeks. Sleeping on a pullout couch at the shop. Doing payroll from a hospital bed and again before the honeymoon. Moving 22 machines in three days with 35 Gaylords and a spreadsheet. And the certifications that decide what work you're even allowed to quote, from ISO to AS9100 to a CMMC bill that's pushing good owners into retirement.
If you're working for somebody right now and wondering what it takes to go out on your own, this one's for you. No fluff, no filters. Just how it actually happened.
What's Covered in this EpisodeEvery shop owner I know is fighting the same war: where do the next machinists come from, and who is going to pay to train them? On this one I sat down with my own congressman, Jake Auchincloss, who came down to the shop with a plan that actually puts money behind the problem.
Why not make big tech build a thousand trade schools across the country, surge one-on-one tutoring to every K-12 student, and make the social media corporations foot the bill? It is bold, it is specific, and it is the freshest idea on workforce I have heard in a long time.
Jake does not pull punches, and neither do I. He calls the social media platforms what he thinks they are: not content companies, but pharmaceutical companies selling dopamine to kids whose brains cannot fight back. Digital fentanyl. We get into how they lobby Congress, the three lines they run every time, and why he thinks the states, not Washington, are going to be the ones to tax their ad revenue and put it back into education.
But this is a shop floor show, so we did not stay in policy land. I told him the truth about what training really costs, the 300 percent you eat on a new hire, the forty grand it takes to fix a spindle after a crash, and why the small shops doing two to fifteen million in revenue are the ones who need to be protected and paid to bring young people in. We argued lottery versus merit for getting kids into trade schools, why we are failing young men, and why the best machinists in their sixties and seventies should be treated like the celebrities they are.
Then we went wide. The new space race and what it is doing to aerospace demand. Drones, defense, and why we should be learning from Ukraine. The K-shaped economy. Tariffs that Jake never even got to vote on. Local banks as the backbone of small manufacturing. Energy costs and the case for nuclear. And a real conversation about AI, where I make the case that it grows shops instead of gutting them, the same way Industry 4.0 did.
This is a long one because it earned it. Two builders, one machinist and one congressman, trying to figure out how we actually fix the workforce instead of just complaining about it. Pour a coffee and dig in.
What's Covered in this EpisodeIn Part 2 of my conversation with Mark Manuel, we move beyond marketing tactics and start talking about something much bigger: the future of manufacturing itself.
Everybody is talking about AI right now. Most of them have no idea what they're talking about. Mark has spent his career sitting at the intersection of technology, manufacturing, and sales, and he brings a refreshingly practical perspective to the conversation. We discuss what AI can actually do today, where it's already creating value, and why blindly trusting it is a mistake. More importantly, we talk about how manufacturers can use technology to become more competitive without losing sight of the human relationships that still drive this industry.
The conversation also takes an unexpected turn into workforce development, trade schools, and the challenges of attracting the next generation into manufacturing. As someone who regularly works with vocational schools and young machinists, this is a topic I care deeply about. We get into the stigma manufacturing still carries, whether trade schools are selecting the right students, and what it will take to rebuild America's industrial base over the next decade.
What I appreciate most about Mark is that he never gets distracted by shiny objects. Whether he's talking about AI, automation, websites, or sales, everything comes back to solving real problems for real people. That's what this episode is about. Not technology for technology's sake. Not marketing buzzwords. Just practical ideas for building stronger manufacturing businesses and a stronger manufacturing workforce.
If you're interested in where manufacturing is headed, how AI will impact our industry, and what shop owners should be focusing on right now, this conversation is worth your time.
