Lex here. This is a point I think about a lot. I hear conflicting advice from brilliant folks I really respect. Some say "go deep on the philosophy" and others "go deep on the technical details of the person's expertise." The latter is something that surprised me, and something I'll definitely do more of in the coming months. In general, one of the things the internet pleasantly surprised me with is that people like depth (even those outside the field). I obviously love the details, especially in ML, CS, math, physics, and psych.
Thanks for the kind words. I work hard on this thing, and hopefully will improve with time.
