When James told me the best early warning for a job-site injury isn’t a safety number, I said what you’re probably thinking — that’s ridiculous, and how would you even measure it? What came next changed how I look at it. Come find out what the number is.

Chapters:

00:00:00 A Gaelic footballer walks into a data-center podcast

00:02:07 Culture as bedrock: measure the inputs, not the score

00:05:30 Scaling culture when you’re hiring thousands

00:06:34 What PepTalk does: feedback from the field, and morale as a leading indicator

00:11:57 The blind spot: why the once-a-year survey misses it

00:16:18 The data: low-morale stretches vs. high-incident stretches

00:19:43 People leave unsafe sites: retention as the early warning

00:36:14 Construction vs. operations: human error and reinforcement

00:40:19 Staying alert in a “fully operational Death Star”

00:45:39 Reading the site like a body: must-have or nice-to-have?

00:51:11 Measuring the truth, and the one big takeaway

Rob Hopewell’s been in data centers so long I keep accusing him of starting at 11 — UUNET, EdgeConneX, now running QTS sales. We get into why this AI moment isn’t the dot-com bust, why the phone in your hand is a data center, and how our industry can finally explain itself.

Chapters:

0:00  From UUNET to now — the early internet, peering, MAE East/West

5:44  “Unprecedented” — solving first-time problems (spiky AI load, the utility)

7:47  Selling power, not square feet — the model that changed the industry

11:48  A day in the life running QTS sales — deals at the C-level

14:16  What the dot-com bust taught him — strategy, relationships, hustle

15:29  The 2016 hyperscale pivot — the Freedom Design and the availability zones

19:04  “Plan B: make plan A work” — the first deal, and Blackstone

24:09  EdgeConneX and what “the edge” really is

30:37  Building speculatively — the formula that won Atlanta

36:04  The messaging problem — what a data center actually is

40:09  Why AI isn’t a bubble (and meeting OpenAI in 2017)

45:08  “One throat to choke,” building sales talent, and the takeaway: culture

A West Texas frac company turned out to be one of the best-positioned energy players of the AI era. Luke Saladyga explains how that happened, why power got scarce so fast, and why the steadiest jobs of the next decade might be ones nobody told you to want.

Somewhere along the way “diesel” turned into a dirty word. Jim McDonald’s spent 30 years on the generators that keep 911, hospitals, and your data alive — and he’s a little tired of playing the villain. We get into what’s real, what’s myth, and why he still thinks everybody wins.

Chapters:

00:00:00 Welcome, and the “luminary chair”

00:01:24 From the University of Delaware to founding MIRATECH (1992)

We’re all chasing the same thing: safe, affordable, local power. Rahul Kar thinks we keep overlooking the easiest source of it — the power already sitting unused inside our own data centers. He’s convinced it’s hiding in plain sight, and he explains it with a kids’ story.

Chapters:

00:00:00 From Boston to Redwood City: an engineer’s “five grand challenges”

00:06:53 Hammerhead AI for non-engineers: the two-toy-car rule

00:09:49 Why data centers run at 30–40% capacity (and why it’s by design)

00:15:41 Plain English: training vs. inferencing, and what a “token” is

00:21:06 Visibility first: how operators stop over-building

00:24:43 Turning stranded power into net-new, flexible workloads

00:31:56 Resilience by distribution: many sites, one brain (the 60-millisecond point)

00:35:07 From virtual power plants to AI orchestration

00:41:46 Small Is Beautiful vs. The Bitter Lesson: the tension driving the company

00:49:08 The “easy button,” and the one big idea: a utilization crisis, not a power crisis

Most people think the cloud floats. Saurav Roychoudhury, a Capital University economist, ran the numbers on Ohio’s data centers and found concrete, copper, and a whole lot of jobs. We get into ripple effects, why community trust is the real bottleneck, and whether any of this is zero-sum.
