Moore's Law states that computer processing power will double every 2 years, but we may be reaching a limit to this exponential growth. Thankfully, some new technologies may be turning that around.

===================
SUMMARY:
Gordon E. Moore was one of the co-founders of Intel and first proposed was came to be known as Moore's Law, which predicted that computer power would double every 2 years.
For nearly 50 years, the industry kept pace with this prediction, but in recent years there's been a slowdown. 2 main reasons are heat and the quantum tunneling effect that occurs at the atomic scales.
Some of the technologies that have been theorized to break through this barrier include:
Graphene processors. Graphene carries electricity far better than traditional silicon processors, but is currently very expensive to produce.
Three Dimensional Chips. Some manufacturers are experimenting with 3-D chips that combine processing and memory in one place to improve speed.
Molecular transistors. Transistors that use a single molecule to transfer electricity.
Photon transistors. These take electrons out of the process entirely and replaces them with laser beams.
Quantum computers. These long-hyped machines could perform multiple calculations at once by using the superposition of quantum particles to process information.
Protein computers. These use folding proteins to make calculations.
And finally, DNA computers. DNA is the perfect data storage device, allowing scientists to store 700 terabytes of information in only one gram. But it can also be used in logic gates and are being tested in a processing capacity.

Transcript:
So back in January of 2016, Musk was speaking at SpaceX’s Hyperloop pod competition, when he said this:
“It’s a really simple and obvious idea and I wish more people would do it: build more tunnels. Tunnels are great. It’s just a hole in the ground, it’s not that hard. But if you have tunnels in cities you would massively alleviate congestion and you could have tunnels at all different levels – you could probably have 30 layers of tunnels and completely fix the congestion problem in high-density cities. So I strongly recommend tunnels.”
But it was something he just kinda said off the cuff and nobody but the most ardent Musk-watchers paid any attention to.
He claims to have built a machine that can dig tunnels for transportation 500 to 1000% more efficiently than current boring machines.
And his logic is that people in cities live and work in a 3D space, in vertical buildings that can house more people. But our city transportation is on a 2D plane, meaning all these vertically packed people are now crammed into a horizontal space.
By creating a 3D transportation grid, we can alleviate the congestion and drive like civilized human beings.
Now, there are a couple of criticisms of this plan, one is that this idea’s been around for over a hundred years, it’s called subways.
And subways are great for densely packed urban areas like New York but for cities like LA, or Dallas for that matter, where things are spread far apart, not so much.
For example, it’s a 20 or 30 minute drive just to get to my closest light rail station, at that point, I might as well just drive the rest of the way. It’s just not practical.
But underground highways under strategic high-traffic arteries could make a big difference. And reducing the time cars are idling in traffic could cut down on pollution as well.
The other criticism is that building tunnels is not nearly as easy as it sounds, even with a giant high-tech earthworm machine doing all the work.
Obviously in urban areas there’s all kinds of things we’ve put under the ground in terms of sewers, gas lines, telecommunication lines and so forth.
But we at least know where those are, what we don’t know is other things like pockets of gas, unstable rocks, hidden fault lines, and so forth.
But… I’m sure all those things will be addressed before any large-scale tunneling begins in LA., there’s a mountain of bureaucratic red tape to get past before that happens.
Which should put completion around the Fall of… never.
A side benefit of this tunnel machine would be for SpaceX’s future Mars colonies, since boring underground would be the best protection against cosmic rays.
Now this is of course nowhere near Elon’s first foray into transportation, I mentioned earlier his hyper loop competition, well, he just hosted another competition in January.
27 teams entered designs, of those, 3 were picked to actually run, and of those, two won awards, one for design, and the other for speed, maxing out at 90 kilometers per hour, or 55 miles per hour.
That’s a far cry from the 900 miles per hour predicted for the hyper loop, but it’s early yet, and it’s only a one-mile stretch of track, so it’s probably not getting up to top speed.

Over the course of three videos on my YouTube channel, I discussed the pros and cons of 7 types of renewable energy: wind, solar, geothermal, biomass, wave, tidal, and hydroelectric. Here, I stitch them all together so you can listen to all three at once.

This week, I got a chance to talk to Ben Sullins from the YouTube Channel Teslanomics, and we talked about all things Tesla, but especially this week's Model 3 event, which Ben is attending and he has some pretty amazing predictions about what might be revealed at the event (hint: a battery breakthrough).

Isaac Arthur runs the YouTube channel Science and Futurism With Isaac Arthur, where he goes into incredibly deep dives on subjects like megastructures, future space colonies, aliens, and little things like farming black holes (like you do). Here we touch on a few of those topics and do a little shop talk about life as YouTubers.
