We're a part of nature. Our technology is toys. We can't predict
  the weather beyond a few days and millions of lines of code. You
  worry about us destroying the planet? [1]James Ragsdale - I'm
  not buying your argument yet.

  You're taking a singular path and projecting it far into the
  future without consideration of other complex forces that will
  intervene. It's only a clear path on paper. Somebody has to fund
  these projects. There has to be agreement of a LOT OF PEOPLE to
  make these things happen on the scale you're talking about, and
  nobody to counter it.

  The checks and balances are also among humanity.
