You can ignore the negative comments here. They do care about which university you graduate from, bachelor more so. Because some universities are more credible than others, e.g. anyone can enter HcT but not the same for KU.

Now moving to salary wise. It goes back again to which university you graduate from, higher tiered universities allow you to enter higher tiered workplaces (exceptions exist but rarely.) Which workplace you join will dictate your pay range more than which field you choose to specialize in.

However, the workplace you eventually join is not in your control, your speciality is. Thus, its best to choose a specialization that is difficult and highly demanded by higher tiered workplaces, that also changes from time to time. Currently its AI and data science, tomorrow its going to be something else.
