Interesting thoughts from Glyph on “the next big thing”.
The fact is, our lifetimes have been an extreme anomaly. Things like the Internet used to come along every thousand years or so, and while we might expect that the pace will stay a bit higher than that, it is not reasonable to expect that something new like “personal computers” or “the Internet” will arrive again.
This is very much counter to popular thinking, but it seems entirely feasible to me.
