That's true. But part of the reason Itanium as a failure is because AMD came out with x86-64, which was so successful that Intel ended up being forced to adopt it (it didn't help that the first generation of Itanium chips was... underwhelming).

This sounds like something Elon musk would do to Tesla just to save $8 on parts

> just to save $8 on parts I don't think you understand what $8 per vehicle represents in cost savings. $8 in parts can literally be 10s of million in savings per year. And then you are basically tied to this supplier forever as switching something so fundamental isn't easy. In automotive, using less screws to save 50c on each vehicle is considered a big win.

Sure, but Tesla doesn’t sell that many vehicles. They only went over a million last year (will be closer to 2 million this year it would appear.

I found that Lex interview enlightening for two reasons. Firstly, Keller is a profoundly talented and interesting guy. And secondly, Lex is a truly painful and incompetent interviewer; virtually every time Lex spoke I begged my screen for him to stay quiet and let Keller speak.

Does anyone have any insight into how hes managed to get such high profile guests?

Some design decisions are also really not obvious. I've seen engineering decisions of the kind... We'll put another microcontroller because we would need less wiring between these 2 boards and the wiring would be more expensive.

A clever one I saw was where they milled a PCB thinner in a section to make it bendy and did not need 2 boards because of this.

I would imagine being extremely good friends with Joe Rogan helps immensely.

I recommend Keller's appearances on the Lex Fridman podcast, and also the chat with his (Keller's) brother-in-law Jordan Peterson.

Keller was great. He was actually great in all public appearances I saw him in. And I find it hard to find something I disagree with him. Usually with people I look up to, there are _some_ things I'm not on board with, but I don't seem to have that with Keller.

I understand that until recently he kind of stayed out of the public spotlight, and I wonder why, because he has such a great presence.

I think the general consensus is that AMD could only swoop in as it did because Itanium was such a disaster of epic proportions, both technically and on a management level. There was no way Itanium was ever going to be successful. x86-64 was just the final nail in the coffin.

Can confirm. Most people probably wouldn't believe the effort that is spent on improving the physical engine models in the ECUs in order to save a few bucks on sensors. Precisely, as you wrote, because those few bucks multiply while a software effort is one-time.

Sounds like that'd have reliability concerns in an environment where the whole thing can receive substantial shocks (the physical kind) over time.

So, US$8M per million vehicles.

That's at least a few engineers salaries. ;)
