Moore's Law is exponential
If you believe it will continue, and that clock speeds won't increase, then you get exponentially increasing #'s of cores (or some other use of silicon estate).
An alternative scenario is that there will be no mainstream demand for more computing power, and only niche markets will buy them. The mainstream will favour cheap, less powerful CPU's. The rise of eeePC and clones is suggestive of this scenario.

- 13ren 18y agoI think the wires would just be a single bus. A single bus works fine for moving data to/from one of many memory locations. Another method of using just one bus is TCP-IP packet-style communication. Of course, there's limited bandwidth, so you want most of your computation done within a processor, not between them.
- anamax 18y agoIf a single bus works for large numbers of processors, why are data centers wired differently? For many problems, bisection bandwidth is a key constraint.
- axod 18y agoMoore's Law is more of an observation. There's nothing to suggest it can continue indefinitely forever.
