-But FORTRAN was already established, probably. (We had cake in the automation department where I work a couple of weeks ago - FORTRAN (FORmula TRANslation; the granddaddy of programming languages) turned 58 (!) years old; it is still being used for a number of things and FORTRAN skills are still sought after, though mostly to maintain older systems, I'll grant you that.)
Just about any industry faces the occasional revolution; diesel ships were new in their day, and nowadays you often find a gas turbine in its place on modern vessels; all within the scope of a few decades.
Communication in general? If you'd told me a couple of decades ago that I would in 2014 be able to buy a wireless terminal providing access to the Internet at speeds of tens of megabits per second, a display simultaneously showing millions of colours at a resolution of 2560*1440 (or whatever the resolution is on my smartphone...), I would hardly be able to imagine it. And here we are, in 2014, and this technology is available to everybody and his dog. There's even a graphical front-end to the Internet, now. And hyperlinks! (Granted, those were around in 1994, too - before anyone corrects me...)
Automobiles? Only about a decade ago, electrical cars were something you only drove if you were a die-hard environmentalist. You had to charge the batteries twice just commuting to work three blocks away, and they all looked like something a kindergarten group had made from cardboard. Today? The look like proper cars, they handle like proper cars (and then some!) and the range is sufficient for just about everybody's needs 99% of the time.
An industry doesn't have to be in its infancy to face (seemingly) constant upheaval. It happens all the time, all over the place. This is a great time to be alive. (I bet the Victorians said pretty much the same thing - and that our grandchildren will do the same!)
