Linus Torvalds: I can pretty much guarantee that as long as everybody does cross-development, the platform won’t be all that stable. Or successful. Some people think that “the cloud” means that the instruction set doesn’t matter. Develop at home, deploy in the cloud. That’s bullshit.

This is true even if what you mostly do is something ostensibly cross-platform like just run perl scripts or whatever. Simply because you’ll want to have as similar an environment
