I can emulate a PDP11, a Nintendo Gameboy, or any other old system. There are perfectly functional x86 emulators for ARM already. Many people used to run Windo

  Emulating a Gameboy is fine, but emulating a large-scale scientific computation may be just a little bit more demanding, I'm afraid. :/

    In gaming world it seems like it's always hard to emulate the last generation, and quite easy to do ones before that. (E.g. Xbox not emulating their predecessors.) It's not my area of expertise but I expect to see something similar here. If you need to emulate hardware you might take a 10x hit, which might be unacceptable for very large scale computations. But in the longer run that might not be a problem as more resources become available.

    It will be slower, but I don't think unusable. Actually, comparing gameboy (and other consoles) is not really a good idea, as they are systems where getting all the processors exactly in sync is important and difficult. Emulating a PC is much easier, as no-one expects to get exactly equal speeds out of processors, as every PC model is slightly different. As I say, I (and many other people) emulated x86 windows on PPCs for years. I ran visual studio and it dragged a little, but was fairly usable. Certainly it won't be as fast, but then again by the time x86 has died and people have moved, hopefully systems will have got fast enough to make up the difference!
