I can sort of see a lot of the fitness industry being disrupted by this. Much of what physiotherapists and personal trainers do is just showing people how to do stuff like squats and push ups safely. Depending on how accurate the pose detection used in this link is, this could maybe be done just by filming yourself doing the movements and the algorithm giving you feedback.

I disagree. I think that the main benefits of personal trainers are to:

1. provide accountability, allowing clients to outsource some of the willpower required to exercise, and

2. motivate clients to work harder during sessions

Good form is significant, but easy to learn.

Some people need to learn in a class with a teacher and some people are more auto-didactic.

As an auto-didact, I go to one physical therapy session to learn the movements and then take those home. Tools like this (when properly advanced) would ensure that my form doesn't start slipping and helps to track improvement in RoM, etc...

Former professional gymnast here. Obviously, the form is one of the most important things in gymnastics.

It's difficult to see if the form is wrong from one angle. I need to circle around the athlete to see all the aspects. Sometimes I also ask if they are using a certain muscle, sometimes they have to "overflex" some muscle to put the emphasis on it, to make them feel it when they do a certain exercise. You can't see much of this stuff, movements are only a part of this. This is cool anyway, better then nothing for people who can't afford a personal coach
