1 I thought everyone would have heard of the FFT, and the IFFT. My understanding is that those are undergraduate Electrical Engineering, because they are so basic and fundamental. So, I initially thought that this would be an early sign of the ML hype train coming to an end.

2 New things are always better.  Always.

3 The FFT, as an algorithm, sort of weirds me out. It does something that by rights shouldn't be possible in less than O(N^2). Because it apparently is possible, many other things that by rights shouldn't be possible in less than O(N^2) (arbitrary sequence multiplication, types of kernel convolution, etc) are suddenly O(Nlog(N)).
I really need to understand what the hell is going on in there someday. Geometrically - because geometry is where some of the weirdness that it causes is.

4 One scientist that I used to work with used automotive op-amps and ADCs for electronics for an extremely EM-noisy experiment. I think he went for them because they are designed to handle a lot of noise: Noise in the power lines, inductive kick from motors, etc. 
Sometimes you don't want the smallest transistors - sometimes you want them to handle some abuse.

5 In 40+ years of screwing around with automobiles, the only transistorized bits that ever worked well were the old GM HEI systems.  But then, I sort of have a fondness for mechanical injection diesels, manual transmissions, and a complete lack of luxury.

6 Automotive is already doing too much of Big Tech's bidding. The legislative fiat pushing so much automation and geegaws on vehicles is a crock.

7 In fairness to the defenders of Holmes, fraud that could kill people has also been committed by Dorsey, Zuckerberg, etc., with their information warfare on behalf of covid alarmism, electoral fraud, and the PRC government.

8 True, but they left a couple of layers of indirection as a shield.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
