The difference in life now and then must be a different world.
And as technology tends to develop faster and faster, who knows
what'll be here in 10 years?
I'm a little unnerved by how addicting all the stuff can get though.
It's a little frightening....imagine being without a cellphone for a
week. Would you be ok with that? I think many would go nuts.
Speaking on technology, transportation seems to lag behind
communications by a lot. Metro, cars, planes, trains etc are
essentially the same as they were in 1975.
I was 18 in 1974.
Personal computers? We were still six years away from the IBM PC.
Cars: in 1975 they still had points and condensors and carburetors. Today,
everything is electronic igniton and fuel injection. Every aspect of the
internal combustion engine is computer-controlled, even to the point where
the valves are driven by servos and a new "cam" can be created by the
computer. You kids don't know enough about how cars work to even
comprehend how computers have taken them over.
Planes the same as 1975? Don't be so stupid. In '75 planes still had
hydraulic systems for control surfaces. Now every airliner flying is fly-
by-wire, with computers controlling every aspect of the flight.
That may be correct for airliners and private jets, but aside from one
or two innovators like Cirrus and Columbia whose planes are at the
very high end of the market, small private planes ARE essentially
unchanged from '75, or even earlier. Their engines are basically the
same horizontally opposed carburated 4 cylinder designs designs
developed in the 30's and 40's, and some airframes are completely
unchanged. Piper still builds the Warrior III, which is the same
airframe they introduced in 1974, which is just a wing-tweak of an
airframe they introduced in 1962. The new ones have much fancier
avionics but the airframe and engine are basically unchanged. And
the engine (Lycoming 0-320) predates 1974 by decades.
(I own a 1982 Warrior II)
You can say the same for Cessna's line. The 172 was originally
introduced in the 1950's and while the current model has lots of
tweaks, they are all the same design.
