So more experts are needed to support it. Also, newer and faster hardware is required to make it run smoothly. Often, it's so much easier to buy speedier hardware than rewrite a whole system from scratch from the bottom-up. The latter would require much more resources in the short run, but in the long run, it should pay off.

This rewiring is a continuous feedback loop. You can program your future self by focusing on your desired outcomes, and your brain will then unconsciously guide you toward them.
