It's not quite like that - they aren't killing off simplicity, mechanical things naturally get more complicated as designers add more functions.
As for the death of the "DIY" generation - yeah, well, that was always going to happen. As society gets more and more complicated, jobs get more and more specialized and time grows short. In ye olden days, the vast majority of people had to learn to grow food for themselves and make their own clothing and hunt and carve stuff out of wood. These days, you don't have to do that, and what's more, if you have a stressful, time-consuming job, you don't have the time nor the patience for doing that.
Cars rarely break down these days anyway, if you buy a good one.
A lot of people complain that this "new generation" is useless and doesn't know how to do things right. Every generation has said that about the next generation throughout all of time. But you know what? They've got it wrong. What they are really angry about is that we have it easier than they do. They resent the fact that we don't HAVE to go through what they went through - life is easier for us, it's always been easier for the next generation, which has grown up with better technology, more social organization and higher education.
Rather than be angry about how "those darn tootin' younguns don't know how good they have it! In MY day, we'd have to fend off a bear, walk 10 miles in the snow and climb a mountain just to get to school! And we were glad to do it! And we had to literally CARVE all our schoolbooks out of wood and make our own ink by harvesting Octopuses on the coast once a month! Bah, these darn younguns, what with their fancy Ipods and internets and the you-tubes, they're just coasting through life! Without a care in the world!" why don't they just say "Well, son, I'm glad you didn't have to go through the crap I went through. Did you know that in my day, I had to walk through the snow for 10 miles up a mountain just to get to school? Thank god you don't have to go through that, that sucked!" That's what my dad says to me - he's always telling me how much better life is for me, and how thankful he is that it is better for me. He honestly longs for the day where we won't have to fix anything ourselves, and we can get robots to do it.
Well, I'm sorry older generation - I had thought that you would have WANTED a better life for your children! That you would celebrate the fact that we don't have to go through the trials and tribulations that you did. It's odd that the older generations would resent the subsequent generations for taking advantage of the advancements they made.
