And there is your problem. You just want to argue. In that, I am not interested. Have a nice one!

By that logic there is pretty much no need for anything in modern society. Heck, no need for humans to exist at all. Yet here we are, innovation is in our DNA. Better to be real about it.

You are not wrong, though everything is temporary. That is not a reason to not try and develop new technologies and methods to solve problems.

The error is in the focus; we have some tested and tried methods we should apply before we work on the far future stuff, indeed.
