I don't post it here a lot so excuse my ignorance, but I seriously don't think this surgery will ever become mainstream for a few reasons. The price, The risks, and the recovery process seems very challenging. The biggest reason this surgery won't go mainstream because of the way the world is going, it's literally crumbling before our eyes, our resources are going to be significantly lower by 2050, and with all the talks about scientists actually pursuing immortality whether it's digital or injected with shots. In 50 years were gonna have WAY bigger problems than our height and I doubt anyone would care at that point, even sooner.
