I am a student at 42, and I have to correct you on one really important point : 42 does not have anything as "pay later out of salary". It is a tuition free school period. Also it is not remote, you need to go to the school everyday, and they provide free accommodation as long as you reach the targeted progress each month.
As far as we know there is no plan to make money. It has been founded and funded by a French billionaire who did not like the way traditional high education works.
I am personally really happy with the program, I started 3 years ago and there are so many different projects and different paths you can choose that I am planning on staying there for some time
