Of course it's easy to blame people for lack of vision 25 years later,
but with the rate at which computing moves in general, cell phones as
powerful as workstations should have been seen to be on their way
within the authors' lifetimes.

That said, Plan 9 was designed to furnish the needs of an environment
that might not ever have had iPhones and eeePCs attached to it even if
such things existed at the time it was made.

But I'll say that if anyone tries to solve these problems today, they
should not fall into the same trap, and look to the future. I hope
they'll consider how well their solution scales to computers so small
they're running through someone's bloodstream and so far away that
communication in one direction will take several light-minutes and be
subject to massive delay and loss.

It's not that ridiculous... teams are testing DTN, which hopes to
spread the internet to outer space, not only across this solar system,
but also to nearby stars. Now there's thinking forward!
