It seems like too many people are planning for the worst possible case, i.e., computers get worse. What if they get much, much better? Can your design be adapted to use technologies that don't exist yet? Is your design parallelizable? If people or machines get used to sub-picosecond runtimes, someone would demand your program gets rewritten. I think that's a more likely death scenario for your program than a reversion to punch cards and abacuses.
