What do you base that on? Who do you think uses these "gig economy" services? First, people with high disposable income - i.e. not the poor or those with families. Second, people who are so comfortable with their smartphone apps that they'll use them to replace very small amounts of time doing the same things in more traditional ways - i.e. not a lot of old people. Sure, there are some outliers, but "young techie" pretty well captures the core demographic here.
You're backpedaling. Earlier you said only young people can afford to use these services. Now you're saying only young people choose to use these services.
The latter may be true; the former certainly isn't.
When the horseless carriage came out, or electric light, or the radio, traditonal-minded folk chose not to buy them. But I don't think anyone would say those inventions made the world into an assisted-living facility for the young.
I'm not backpedaling; you're moving the goalposts. I said all of those servicesall the time. In other words, not occasional but habitual use, and that demographic is dominated by the young Google/Facebook/VC techno-elite. You don't like where that thought leads, or how the conclusion reflects on you? Too bad. The facts are the facts.
And anecdotally, I've noticed that my neighbors who happen to own two or three cars tend to be older, and the ones with one or none tend to be younger. The San Franciscans I know with a second home somewhere tend to be older; the ones who can barely dream of ever owning a home tend to be younger. Go to the opera or look at the nice seats at AT&T Park, and see who's sitting there. By and large, you're not going to see many young people.
Anyway, you didn't answer my other question: when things like dishwashers and refrigerators were invented, would you characterize their impact on the world to be turning it into an assisted-living facility for the young?
