I'm glad I've seen what I've seen but I'd rather pull out the phone to do a calculation rather than a slide rule, like I used for a while.
That's a great quote.
The perceived loss of interest that some see in the young is probably an inevitable consequence of mature technology. Does anyone really think today's youth are less intelligent than young people in the 1970s or 1980s? If you think that and were around back then, take a moment to think of the biggest goofballs you knew back then and compare them to the biggest goofball kids that you know today (not much difference, see what I mean).
Mature technology has made it unimportant to know anything about how a system works, so you can focus entirely on the function of the system. Three examples are audio, computers, and cars.
Setting up a stereo was never all that complicated, but if you go back 40 or so years, everybody interested in audio knew how to hook up components, cut speaker wire, put the speakers in phase, do basic maintenance (cleaning tape heads, adjusting tracking force on a record) and so on. Plus, most everyone could rattle off the specs of their equipment (watts per channel, THD, and so forth). Now, most just put some earbuds in their phone or point the phone at a bluetooth speaker. But the bottom line is young people like music and get the benefits of music without needing to know much about audio.
If you had a computer back then, you had to be pretty knowledgeable to get anything out of it. You probably knew how to write code - Applesoft BASIC, GWBASIC, or whatever came with your system. You also probably knew all the specs on your computer, and may even have had the computer's memory map imprinted in your own memory. Now the computers are about a trillion times more powerful but only a very tiny percentage of users knows how to write code - instead focusing on web browsing, video games, Instagram, Facebook, and so forth. But the bottom line is young people like computers and get the benefits of computers without needing to know much about them.
Cars back then were not nearly as reliable. Many were in the junkyard before 100,000 miles and now many cars seem to get to that milestone without any breakdowns at all. Back then, even if you weren't interested in auto mechanics you had to know some basic stuff out of necessity - how to change the oil and spark plugs, the air filters, replace a flat, and so on. If you were into it all you probably had a basic understanding of an how internal combustion engine worked. Few young people probably know anything about what's under the hood now. But the bottom line is young people like to drive and get the benefits of driving without needing to know much about cars.
I'm not sure why anyone would blame the younger generation for this, as they are growing up in a different world where the technology has greatly advanced, but also where the inner workings are too complex for the average person to understand or learn. But I do think the maturation of technology has a downside - it makes it tougher to turn your passion/hobby into a job when you don't understand the way things work.
