I used to run Index Gate with OG Stark in a custom. It wasn’t performed even close to how it was performed when I run it out of custom. Just try it a major shop version, you will find it to be very nice. If you want, you may add Beyond Limitless, it should give you a massive boost in productivity and knowledge hunger.
Regarding your question, I’d start it with Python. First, get a solid knowledge of Python, to the point you haven’t to think about 'how can I solve [basic python problem]?". Just like you don’t read every letter one by one when you read a text, but you read all the word entirely at once. Same here: you know basics excellent, you don’t spend time on basic constructions, you spend time on making an algorithm. Programming is literally about building algorithms, through using programming languages. You may know a programming language, but not necessarily know how to programming. Just like you know English, but can you write poems?
When you learn Python enough, you’ll be able to see what to do next.
And yeah, if you want to go into AI, you’d better start learning Computer Science degree level math now. But before you have to know high school math profoundly.
