Drilling the hole is the hard part and something this company is claiming they have a new solution for. It will be interesting to see if they manage to drill holes.

Once you have that, the rest is easy. But drilling deep is hard. When I say hard, think expensive. The problem with geothermal so far has been not that it is impossible but that it is expensive to drill holes. Also pumping water in and out holes requires pumps and pipes and machinery that needs maintaining. So, there's a cost associated with that as well. And of course the amount of energy you can get out is proportional to the diameter of the hole. To scale you need to drill more holes. Which is expensive.

That's why geothermal is mainly used in places where you don't have to drill very deep.

So, technically feasible, maybe. But the real question is whether it will be economically feasible.
