Huh?
I don't think you got my point at all. Our brains are plastic in order to use all tools more effectively. As soon, as we can free some space, it will be used by a different function.
Do we have a shit memory? Yeah. But our logic, multi tasking and planning should be better now.
It's the difference between a worker and a manager. Our brains need to learn how to manage tools, but as a result, one manager will ALWAYS get more work done, then one worker.
