But only as long as training actually improves models significantly. As soon as those improvements stay below a certain threshold, the better move is to invest your R&D money into other things like harnesses or new tricks one can play with existing models and the immense cost of training is just not worth it to be 0.5% ahead.
I'm absolutely certain that we will reach that point, just not when. Could come sooner than we think though.
At that point they would lose all advantage stemming from their ability to boil the ocean though.
