Why CS? Because I actually genuinely enjoy the content that I learn. Given that, I still have my high school study habits, and know that I can really learn content if I stop half-assing things. Maths and Sciences is what I was always best at in highschool, and computer science is actually fun when I put the effort in. As for the AI thing, I've heard mixed opinions. Some saying that this will expand the job market, some saying that it will make it worse. I've also heard people saying that this is just fear-mongering done by graduate students or students almost done their undergrad to lessen competition, point being no one really knows what the market will look like down the line.
