I really enjoy Alec's videos and quirky humour. Beware though, this kind of channel is a massive, addicting time sink. Other similar channels that HN might appreciate (the first two are quite well-known, the last one I found recently and is definitely bingeworthy):
- Smarter Every Day https://www.youtube.com/channel/UC6107grRI4m0o2-emgoDnAA
- Tom Scott https://www.youtube.com/user/enyay
