With all due respect to John Carmack and Michael Abrash, this reminds me of a song by Tom Lehrer:

"Once the rockets are up, who cares where they come down? That's not my department, says Wernher von Braun."

I'm sure Facebook will give Carmack, and now Abrash, all the tools they need to build their rockets. Where they will aim them is another story, and will be decided by others.
