Yep, this is why no other software can compete. People don’t realise that mathematica consists of huge lists of hard coded cases for different mathematical problems. It’s not like they managed to find the general formula for everything. And there are functions that I rely on that literally no other software has, that I haven’t even managed to find any papers that would even hint at their implementation, that magically work for almost any input. For example, MinimalStateSpace seems to be able to find the minimum required form for basically any input state space, which is highly non trivial. It’s a huge amount of work going into niche mathematical problems that even most people in STEM won’t have heard of. I don’t see how others can compete
