- lots of conferences (all talks) get posted, so I tend to watch enough of those (not the 'big' marketing stuff like Google, more specific tech or domain driven like some language, paradigm, product...). It's my way to keep in touch with many of these spaces without spending more than a few hours per year: from the mouth of the lion (main keynote is usually 'enough' for the 20% effort). E.g. I heard Rob Pike maybe 6 months ago, so I know where Go is at on its ~10-year journey so far. It's also a great way to discover in-depth features when you're digging into a topic (again ideally, 1 as-fast-as-possible talk from developer themselves). You generally have to seek the relevant channel, e.g. for Pycon 2019 https://www.youtube.com/channel/UCxs2IIVXaEHHA4BtTiWZ2mQ/vid...
- Coding Tech posts a lot of talks from all around the programming scene, and the curation is surprisingly good (some talks are really awesome, maybe half is quite decent). https://www.youtube.com/channel/UCtxCXg-UvSnTKPOzLH4wJaQ
- Level1Techs (and Level1Linux): Wendell is a nerd like us, but he's smarter and funnier at it than most. I love this guy. Real, real good perspectives. https://www.youtube.com/user/teksyndicate
- Gary Explains: he's just the best for all things mobile, ARM, etc. (very high-level, but he knows programming and sysadmin so he's not shallow like most popular YouTubers with those topics) https://www.youtube.com/channel/UCRjSO-juFtngAeJGJRMdIZw
- Anton Petrov is the best astrophysics and related science news I've ever had (10 minutes a day is enough for me). Almost real-time with papers, and plenty of skill to explain the stuff simply. A really "wonderful person"! https://www.youtube.com/user/whatdamath
- PBS Space Time, probably the best layman content to understand theories in astrophysics, and Matt is awesome. He studies black holes! (also consider PBS Infinite series which is inactive now). https://www.youtube.com/channel/UC7_gcs09iThXybpVgjHZ_7g
- 3Blue1Brown, obviously, selectively for topics I need/like. (but I tend to binge his stuff because it's so good)
- TED is not what it used to be, but worth watching a few sometimes (TEDx has disappointed me too many times with clickbait (waste of my time), so I really avoid it now unless someone human recommends a video).
- People like Socratica (math, Python), Andrew Dotson (physics), Zach Star (math), Kai Hendry (Linux, AWS..), "Machine Learning with Phil". It fluctuates in time as I discover new people or as their content becomes boring to me.
- Special mention for Robert Miles, AI safety researcher at Cambridge iirc. It's mostly abstract math / philo stuff (that funny boundary between the two), and really mind-blowing at times (I mean literally, not the smoking gun, just your mind melting down from thinking through the problem). I'm in awe at the talent of this young dude, so fluent with such topics. https://www.youtube.com/channel/UCLB7AzTwc6VFZrBsO2ucBMg
### More general stuff:
- Stefan Mischook has the best freelancer (and beginner developer) advice you can find, imho. He's a legit down-to-earth guy with a knack for telling it like it is in simple words. https://www.youtube.com/user/killerphp
I also watch a few musicians who do impressive stuff, but that's more fleeting, no real sticker here for me. Just impressed at all the tatent out there!
My MO is simple: I only look at my "subscription" page (ignore the 'home' page with suggestions most of the time). Occasionally, I'll look at the right pane suggestions and try things, but I'm quick to close the tab if it doesn't feel genuine.
Also, lots of backtracking. When I discover a channel that's great, I'll just spend months going through the catalog...
