The problem is, that ancient processor architectures are used for modern
processors and software.
The correct solution to the concurrency problems would be a new
architecture, designed to naturally deal with concurrency.

It have a very high cost to do so. It would prevent many thead local

good idea.

We need languages and frameworks that deal with that.
