Modern CPUs and GPUs require highly sophisticated machines and processes, even today only handful of countries can produce them.

The more complex the product gets, and more exotic materials the product requires it becomes harder to be self-sufficient.

Define self-sufficient.

If you define it as energy, food, water and oxygen self-sufficiency. I believe it is possible.

But if you expand that to more complex products like computers etc. It would not be achieveable for a long time, I believe.
