In my mind there would probably be a strong
correlation between engineers
making products unnecessarily complicated (whether they want to or not) and
end users deciding en masse not to sink the time into learning how to
maintain increasingly convoluted and esoteric designs.
To me, the biggest surprise about Unix history is that the Bell patent
office secretaries were able to use ed and [nt]roff. I cannot imagine the
general populace doing that.
Folks on this list will be fine, there will always be programming
environments for us. For the rest of the world, simpler is better and
simpler isn't Unix.
