Okay Trump is recent, but his whole change of focus since buying Twitter is where public opinion on him shifted. That started a shift in public statement more toward the libertarian or perhaps conservative and that made him unpopular with a lot of the liberals who previously liked him for pushing environmental causes.

Now that he pushes conservative and libertarian ideals, supports a Republican candidate, he becomes persona non grata. That may well be valid, but it should not take away recognition of his other accomplishments. If he’s now an asshole, he can be a visionary asshole. Becoming an asshole doesn’t mean he isn’t or wasn’t a visionary.

I’m not saying he’s not an asshole. But he is a visionary.

And right now, if he wasn’t up Trump’s ass, you’d probably be saying he’s a visionary without sarcasm.

Read your damn history.

SpaceX is basically 100% Elon’s creation. He was founder, Tom Mueller (who designed the Merlin rocket engine) was the first employee period

Tesla was Elon and a few other people who had seen a good electric roadster, but it had been a one-off that that company was not going to produce. They decided they wanted to produce an electric roadster, so they did. Initially, Martin Eberhard was in charge of the company and Elon was just an investor. Search archive.org for the original Tesla blog. It’s all laid out. I know this because I was following them while it was happening.

Eberhard was in charge, and they were going for a setup with a two-speed gearbox. There was to be no clutch, just a synchromesh to allow shifting. Problem is, shifting at 10,000+ RPM under heavy load is mechanically stressful, and they were having a lot of trouble getting the gearbox to work reliably. After a good year of screwing with this, they were burning through cash and not getting close to actually shipping a car. That’s when Elon stepped in, pushed Eberhard out, and took over Tesla. Elon quickly switched to a setup with a single speed non-shifting gearbox (much easier to build, much less expensive, and will basically last forever as long as you lubricate it) and a larger and better cooled electric motor to deliver the required torque that they wouldn’t get from a lower speed gear. That setup is still in use today in all Teslas.

The problem is that ideas that are under people like musk, are doomed to always fail

Like electric cars, like reusable rockets…

the end of Moores law

It’s been talked about a lot. Lots of people have predicted it.
It does eventually have to end though. And I think even if this isn’t the end, we’re close to the end. At the very least, we’re close to the point of diminishing returns.

Look at the road to here-- We got to the smallest features the wavelength of light could produce (and people said Moore’s Law was dead), so we used funky multilayer masks to make things smaller and Moore lived on. Then we hit the limits of masking and again people said Moore’s Law was dead, so ASML created a whole new kind of light with a narrower wavelength (EUV) and Moore lived on.

But there is a very hard limit that we won’t work around without a serious rethink of how we build chips- the width of the silicon atom. Today’s chips have pathways that are in many cases well under 100 atoms wide. Companies like ASML and TSMC are pulling out all the stops to make things smaller, but we’re getting close to the limit of what’s possible with the current concepts of chip production (using photolithography to etch transistors onto silicon wafers). Not possible like can we do it, but possible like what the laws of physics will let us do.

That’s going to be an interesting change for the industry, it will mean slower growth in processing power. That won’t be a problem for the desktop market as most people only use a fraction of their CPU’s power. It will mean the end of the ‘more efficient chip every year’ improvement for cell phones and mobile devices though.

There will be of course customers calling for more bigger better, and I think that will be served by more and bigger. Chiplets will become more common, complete with higher TDP. That’ll help squeeze more yield out of an expensive wafer as the discarded parts will contain fewer mm^2. Wouldn’t be surprised to see watercooling become more common in high performance workstations, and I expect we’ll start to see more interest in centralized watercooling in the server markets. The most efficient setup I’ve seen so far basically hangs server mainboards on hooks and dunks them in a pool of non-conductive liquid. That might even lead to a rethink of the typical vertical rack setup to something horizontal.

It’s gonna be an interesting next few years…
