One of my ideas, want to run it past you.
Since i won't be able to make Super-dense-Super-small ICs with home grown technology...
My idea is to design a chip that is scalable sideways.
Like the idea of a 1 bit computer. Then using 32 in parallel to make a 32 bit computer.

So, i was thinking of dozens of small processors built up on glass (chips on glass)
You would have a processor dedicated for all kinds of things we use a CentralPU for now.
Like one chip handles I/O. One chip handles memory. One chip handles hard drive access.
One chip dedicatedly run the linux kernel.

This is one of those ideas that is hard to tell if it is just a neat thought experiment, or OMG, this is the way all computers will be in the future...
