Jim is a tour de force: https://www.youtube.com/watch?v=Nb2tebYAaOA

I wish the interviewer was more technical. He doesn't do interviews very often. Lex has a PhD in machine learning but doesn't seem to be familiar with branch prediction, apparently.

If I was a curious noob, how would I tackle this?

My provisional answer is that I'd host a conversation between experts.

For example, I'm now very curious about Apple Silicon M1 wrt to Java's Memory Model and Project Loom (structured concurrency). But I don't know nearly enough to even ask smart questions, much less understand the answers.

So my dream future perfect interview would have Ron Pressler, Doug Lea, and one or two people really smart about M1 (the only name I know is Dan Luu) sit around and chat it up.

I'd ask them open ended questions, like "What's new and different?" "What happens next?" "What are you excited about?"

The conversations would likely happen over multiple sessions and different mediums. Because the experts would share and ask each other stuff which would prompt followups.

As podcast host, I'd try to be catalyst, try to remove myself from the convo as much as possible. I can't think of any examples, role models. While I'm a huge fan of Ezra Klein and Adam Gordon Bell (Corecursive), I'm not confident I could lean in like they do.

One tactic both Lex and AGB do really well is prompt their guests to explicitly define jargon. I suspect that some of the perceptions of Lex's ignorance are him trying to make topics more accessible. eg Working close to the metal with AI, I'm quite confident Lex knows about branch prediction.

I often find it hard to believe that a single person can make much of a difference in such intricate problem domains as chip design but in his case the evidence is overwhelming. Also goes to show what a shit show Intel has become since even he was not able to right that ship. I think in the CPU space it will be all ARM and RISC ten years from now and since Intel never really managed to become a dominant player in any…

Was he exclusively working on "that ship" ... wait, I thought you said "chip".

Earlier quoted context omitted.

One of the tendencies of shrinking companies is exacerbated executive infighting. If the company is growing, there are new X-of-Y positions to move up to. If the company is stable or shrinking, people start watching out for their own careers with knives out. AMD possibly avoided this because of size & realization of what needed to be done. Intel's too big & old: I would be very surprised if they weren't much more int…

This is an absolutely on-point observation about company dynamics that a large number of people in the tech industry have never had to experience. It's why growth is so critical.

Past a certain size threshold the organizational and social dynamics of human relationships seems to be the predominant factor in getting anything done. i.e. There’s a limit to how big of a headwind we can cope with.

I think you are right about Lex and also thanks for the compliment!

Even if you know about branch prediction, then asking the guest to explain it, maybe even pretending not to know about it, is a great way to have concepts introduced and make things more approachable.

Lex wouldn't be as popular as he was if he didn't have a good sense for the level of knowledge his ideal listener has about the subject.
