The good old days are gone, thank you!
In the 1970s/early 1980s I was a real expert at operating a slide rule and a card punch machine. These skills gave me an edge over others. Those days are gone, and I shed not one tear.
I once wrote a whole compiler on punch cards. A whole box of 2000 cards. I tripped and dropped the bugger down a stairwell and it took be a few hours to get the cards back in order so the compiler worked.
Possibly the most challenging development environment was when I was working for a company in Cape Town in the mid 80s. Some of the code came in libraries on tape - posted from UK. We did not have the source code (much of which was written is assembler). When we found bugs in the code we'd patch it in place to execute a jump to some spare memory where we had the patch which we entered byte by byte in hand compiled machine code. Once the patch worked, we typed it all out and drew some pictures, then faxed the whole mess to the programmers in UK. It generally took a few voice + fax discussions to agree on a fix, then they'd send us another tape.
Presentations back then were primitive, but people concentrated on what was important. Maybe a few acetate slides for the overhead projector. Now we have people spending hours and hours making Powerpoints... Is the communication any better? Doubtfully. Is the productivity better? Certainly not...
Does backspace buy us much? Not always. Sometimes the ability to continuously refine stuff at a low expense wastes so much time.
As for income? Ok, I was not around in the 1950s, but back then very few people had cars - now one car per person of driving age is about standard. People complain they can't afford all they want, but back then there just was not much stuff to buy, and what you could buy was crap.
Things like cars were pretty crap. In winter it was pretty standard that cars would not start. A car that achieved 100k miles was a miracle.
A few weeks back I tried to explain to my 20 year-old-ish kids how crap my university buddy 1960s VW beetle was:
* It had 6V electrics. If it rained any to turned on the wipers the extra current draw would cause the headlights to dim on every cycle.
* The petrol "reserve" was basically a lever that went through into the fuel tank. To use the reserve you twist the lever and it basically tipped over a bucket with the reserve petrol in it. If you didn't twist it back the reserve would not work.
* The back seats were prone to catching fire because they were made from inflammable stuffing and wire springs - with the battery stored underneath.
* The windscreen washer was a pressurised container that stole its compressed air from the spare tyre. When you needed a spare it was typically flat!
* etc etc etc.
Yup, the good old days - you can have my share of them!
