Its good to see someone trying to walk a different path. B.Sc computer Science, contrary to popular belief is actually a good degree. And it is a 3 year program. It is no surprise then, that most companies won’t prefer you for a job with this degree but that is no reason not to consider it. If you are interested in research, by all means choose this degree and go for it. It is a good option if you want to learn about the theoretical aspect of computer science. You can do the required coding yourself and teach yourself. Other than that, this is a good degree if you want to build up a research acumen. Obviously, you might need to do a Masters degree if you want to go for a job and a lot of companies do hire candidates with M.Sc in computer science as a degree.
Hope this helps!
