If you like writing code, CS is the most sensible option regardless of LLMs. If you want to make money, the picture is less clear - hopefully LLMs will reduce the demand for code monkeys which is skewing dev salaries to such absurdly high levels (though admittedly this is less of a problem in the UK). If you want to feel some sense of pride or accomplishment in your working life, I'd advise engineering instead. I work for a FAANG company but my friends all have real jobs like "teacher" and "engineer". I'm much wealthier, but they are much happier. For now, don't worry about it and just go to a good uni and enjoy the 4 years (definitely do an undergrad-masters course, not just a BSc). Keep an eye on the economic climate in years 3 and 4 - if you think you have it in you and no obvious better options are available, do a PhD with the intent of ducking out of academia immediately afterwards. Good luck!
