> All that stuff has to react rapidly

Just to add color ... equipment that has to do a lot of work quickly, even if intermittently, has a huge draw. Like your well pump or air conditioner when it starts up.

Now imagine you need to start a few dozen air conditioners simultaneously. The startup energy can be 10x the operating energy.

I've been doing the math on some of this for home solar. In my case I can ramp up the voltage over a few seconds but AIUI rockets still need instant action in many cases.

It's possible future reusable spacecraft could be more proactive, lowering costs and necessary chassis strength. Most of our technology starts off brute force and gets refined with more elegance but also more complexity over time. We're still early days in spaceflight.

Actually, at the extreme scales, which is the total volume of the observable universe, the universe is quite homogeneous. As I recall, to the order of 1-in-10000 variance. This is why Inflationary cosmology was developed, to explain the distinct lack of lumpiness in the universe, which is what we would expect if the Big Bang alone were responsible.

When CUDA started taking off we had ATI hardware, to support their open source pledge, and looked into ROCm.

Just getting the drivers to build on EL-anything was an extreme effort, and it wasn't my first rodeo.

Without betraying confidences, I was told second-hand that there were only ten people on the GPU driver team across all platforms and that they were doing their best and not sleeping enough as it was, with Compute way behind gaming bugs on the priority list.

I couldn't independently verify of course but the theory fit the data.

I immediately empathized with the suffering of the devs and went out and bought nVidia cards, annoying binary drivers and all.

Since then I've felt like that some bean counter at AMD wrote nVidia a trillion dollar check.

If you're not a tiny company *overstaff* your engineering departments so you don't miss new opportunities as they arise. The opportunity costs exceed the opex costs.

Same here but this lack of support will matter much less than dropping i486.

There are still embedded systems sold today that only meet i486 specs. I don't use them but some industries do.

Sure a $12 ESP32 can handle those tasks but it's a revalidation thing.

Not that anybody from those vendors stepped forward to maintain a tree.
