I knew real science stars who ran Mathematica on 486 with huge success. But that's a different story. This project targets hobbyists and kids educating themselves and this normally involves watching YouTube tutorials/lectures and googling information up. For some people this can be good and teach them patience, for many this will be an obstacle and divert them to alternatives. Mathematica is great but has keep the competition in mind. I am afraid it will decline heavily sooner or later.
