I’m a web dev and I’m wondering if there is really any practical way of levelling up to become an ML Engineer. Seems there are ‘schools’ out there but based on what I read on Hacker News these places won’t remotely prepare me to make that transition.

Not complaining just would appreciate some of your thoughts on what are good options to consider to make that leap.

TBH the code behind generative stuff is "fairly" simple, I made a GAN for my Masters degree back in 2019 that produced 16x16 tile assets for x-bit styled videogames. The rough part is CREATING the math that supports the learning models, its very easy to implement it after the fact. If you have a strong data structure foundation, and are decent with math then it shouldn't be a hard transition to pick up ML. It's the flavor of the year and everywhere you look schools are hustling for your money, can't say I've tried any of them/have an opinion of them so GL with that.
