Young people don't like pinball anymore, there's other stuff to do.
Young people didn't like pinball 15 years ago either.
And yet the hobby is absolutely filled with people in their 30s now.
SO it really doesn't fucking matter. Pinball has contracted a lot since it was a "go to" for young people 30 years ago. But it seems like there's always a generation of 30 year olds with disposable income who get interested in it as they age into noticing how awesome pinball is, and are ready to step up. It's been happening ever since I started collecting in my mid-20s and it'll keep happening.
Or it won't. What do I care? All I know is trying to force teenagers to get into pinball is a waste of time. They aren't gonna drive an '84 Iroc to the prom either, or get excited when Loverboy comes to town. Once again, it doesn't fucking matter. Stop worrying about it.
