Future career advice

Hi there. Im in Yr11 (Uk) and want to go into tech. Ive got good grades and after sixth form, hoping do get into a apprenticeship (most are in software engineering) or top 5 uni (with internships) to help bypass the entry level tech saturation. However, the more i read, the more i hear of these horror stories of people with xyz experience getting laid off and unable to get jobs and wondering what the tech market is like currently for mid level/senior proffessionals. Of course, i wont enter the job market for probably another 5 years at least so any market predictions or forecasts would be useful. Of course, tech is a very generalised term and it seems like ai, cloud and cybersecurity are the most in demand/high paying areas so probably wanna head in that direction (if thats the right think to do) I'm just wondering if with the state of the market and the rise of ai, this is the sort of career i should be going into, as ive only a few months to decide my A levels(as i dont really fancy picking sciences unless i have to). Ive been encouraged into medicine but tech just feels so much more interesting to me as opposed to science. Any advice on the best way to set myself up for future success? How would i navigate myself into those roles (if thats the right thing to do) and avoid all these horror stories? Thank you!
