Quoted from Richthofen:
Adults in 30 years will collect antiquated iPads and not pinball machines.
A very, very select few will (like those that collect newtons or old brick phones), but in 30 years, digital tech will scarcely resemble what we have now. Pinball has been extremely similar in concept since the advent of flippers. My children will be nostalgic for the pinball machines dad had or still has. They might want one. I know my son will for sure. Will the community get huge? No, but these are very expensive toys.
