Other Good Consequences
Even if Moore's Law coming to an end doesn't lead to ingenious new architectural ideas, it will have the result that computers won't become obsolete every few years. This would make it easier to justify spending the money on getting a good one.
Or one possible result might be computers that could be upgraded incrementally by adding more CPUs. So you start with one 8-core CPU, then you put in another one, then you get two and add them, and you've got 32 cores to do your bidding.
