So, how were the computers built were need to build the computers that built
the computers? This isn't a chicken or the egg scenario. Computers can built
using only gears and cogs, with no electrical power at all, like the first
Babbage Engine. The US Military still uses mechanical computers for
targeting, and its 1999. And yes, your production will be very slow, and of
very low quality, following the scenario I detailed. But, it can be done, and
that is the point I was trying to make.

Ahh, but what would the coal and oil industry have the say about that? You
seem to forget that making use of technology is a much slower process than
development of the same technology. Besides, Sweden is now lining their
highways with PVs for low cost, day time power. And not because the
technology is now here, but because ecological concerns have forced the need.
And again, yes, the first solar cells were produced in the 1950s, but the
theory was around for much longer than that. Just because we did try to build
them until the 1950s, doesn't mean them we couldn't build them earlier than

I work with plasma vapor deposition technology, and you probably be surprised
at the number of third world countries that have PVD tools. But that doesn't
mean people have seen the need to spend money for the betterment of those
countries by using those tools for anything other than export product. Don't
mistake lack of resources for lack technology. If the western world decided
that every country in the world must have this technology, then without a
doubt, some of the third world nations of this world would refuse. Good
intentions have never made good money without a little exploitation.

Just wait for the series to get around to explaining, instead of rampant
speculation based on a dislike for the series' creators.

You can do vapor dep without computer control, you just lower your quality by
a leaps and bounds. As to today's technology being interconnected, true, but
that is just our technology. Not the technology over 2000 years from now. Or
even in an anime show.

Just watch the show. All should be revealed in do time. If not, then bitch at
the end of the show, not at the beginning.
