This list with no context is bordering on useless. Here are some channels i've watched and enjoyed:
1. interviewing.io - they do tech interviews with big5/6 tech co candidates and step through them: https://www.youtube.com/c/interviewingio/videos
2. CS Dojo - ex-googler who steps through CS topics (data structures, algorithms) at the intermediate level and applications in python + javascript: https://www.youtube.com/c/CSDojo/videos
3. Academind - Heard of tech x and have no idea what it is? Chances are there is a 20-30 min video on this channel explaining it clearly. He also does longer form "build x app" videos: https://www.youtube.com/channel/UCSJbGtTlrDami-tDGPUV9-w
4. comma.ai / George Hotz - ML + AI livestreams from geohot: https://www.youtube.com/c/commaaiarchive/videos
5. Lex Fridman - ML, AI, python and tons of awesome interviews with luminaries: https://www.youtube.com/c/lexfridman/videos
6. Joma Tech - data science, big companies / startups as a dev and some funny vids: https://www.youtube.com/channel/UCV0qA-eDDICsRR9rPcnG7tw
7. Wes Bos - decent css explainer vids for whenever you're _how do i align the fucking boxes_ + react / js https://www.youtube.com/user/wesbos
8. Rect conf - Sophie and Dan's presentations are great: https://www.youtube.com/channel/UCz5vTaEhvh7dOHEyd1efcaQ
9. Nickolas Means - not a channel but two presentations that are good:
9.1 How to crash a plane : https://www.youtube.com/watch?v=099cHWSbAL8
9.2 The original skunk works: https://www.youtube.com/watch?v=pL3Yzjk5R4M
There are tons of shitty tutorial videos and channels to avoid if you just rely on search (the comments are full of what appear to be dev contractors out of their depth begging for solutions)
