I looked at the latent.space site and it didn't seem to be updated/maintained. What I would like is a reputable playlist/roadmap of things to consume to go from Senior Engineer to AI Engineer. Foundation you need what, a primer on Linear_Algebra+Calc+Stats+Prob. At a minimum you have to know the language. Then, do you need anything of classical AI? Anything of classical ML? Do you even need to have any knowledge of Deep Learning other than it exists? Or transformers? OR do you just need a bunch of tutorials on how to implement GPT API's, structuring and managing prompts, etc. I know all this information is out there but has anyone linked it together? If so, is it paywalled? I did a quite search on AI Engineer and before I knew it a site was asking me for 20k+ and 1.5 years of my life. I already have a master's in CS, so I assume I can make faster strides and do it for less. Can anyone advise?
