Ask HN: What are the best coding related MOOC / Course platforms these days?

Hey there, I started learning how to code in 2010. Back then, the courses on Udacity were expensive but really good. I used Egghead. Edx. SQLMastery, TylerMcGinnis' React courses and many more to become an intermediate programmer skilled enough to run a SaaS product all by myself

What are the good code / technology / devops related learning platforms that are still good or that people using nowadays? I feel like I need to level up as a programmer for the age of AI and would love to know what people are finding useful these days, the signal to noise ratio online has really massively changed and so it would be nice to get recommendations of newer platforms if this post catches on. Thank you!!
