I think they basically agree with your point here -- they mention Descartes and Kant to say roughly "I hold basically these ideas, but I don't mention the philosophers' names when I talk about them because 1) I came to them independently, and 2) the people I'm talking to are not familiar with the context so situating our conversation there isn't helpful." Their argument is that you can have philosophical conversations without relying on the context of the canon, and that in a first-level discussion they wouldn't bring up Descartes or Kant.
> I think the variety in barista coffee is different from the variety in, say, fashion or wine because with fashion and wine there is social signalling and all kinds of things going on
Sounds like OP just doesn't care about coffee thst much. Fine for them, but any subject has a subculture; there are definitely social signaling games within the coffee world
I agree that a smart, ambitious person can become expert in more than one field in their life — but jumping to a new area of mathematics is on an entirely lower level than jumping from algorithmic finance to cutting edge biomedical, especially at the time Erdős was working.
Worth mentioning Nebula [0], which is $10/month to support a large roster of educational (or education-adjacent) creators. The site is "creator-built and creator-owned", according to their homepage, and a number of YouTubers I like and respect have promoted them. No ads, and there's some Nebula-exclusive content which might be interesting as well.
Oh, also, two other things: First, CuriosityStream has a bundle deal with Nebula where you can get both at once: [1]. You have to find an appropriate promo link from one of the participating YouTubers but that shouldn't be too hard.
Second, I know you mentioned wanting to find dedicated services, but if you're spending a decent amount of time on YouTube and you can afford it, I find Youtube Premium well worth it. Not having ads makes such a huge difference to the experience, and it also pays creators better!
those first four are things that i didn't even realize bother me but i feel like it'll be a massive QoL improvement to have them turned off. thank you!
