As the possibilities for smaller transistor get narrower companies will get more open towards smaller clients with small budgets, so taping out homebrew CPUs or SOCs or integrated circuits will be possible.
so far, the opposite is happening in the "cellphone"/pocket pc space... it is getting hard to get a phone that you can root without having to resort to "holes" that can get patched at any time...
Can you elaborate please?
Well, most people aren't going to make their own chips any time soon... so you have to buy what is available and cellphones are getting more restricted/locked down everyday in the name of security (they are getting closer to what they used to be before Android came out)... not sure if that answers your question though.
