> Secondly, the industry has changed. You need to know more things than you did previously. Are you sure about this? I think it's actually the opposite: today you don't need to know anything about digital electronics, information theory, theory of computation, computer architecture, OS design, formal methods, PLT, etc. to be a very successful software developer. You just need to know how to deal with one DBMS, one high-level language, one ``framework'', and after literally a couple of years in the industry you will be making a 6 figures salary.
