The days of sited machines is virtually over. The chances of youngins getting the bug is fairly slim due to availabilty of play in the wild. In saying that my son (aged 25) who lives in the US had never played a pinball till recently. To watch him play his first game was funny. He would stand stiff then just push the flipper buttons. By game 20 the hips and pecs were thrusting combined with a lot of verbal outbursts. My dad is in his mid 70s and still plays daily.
Nobody seemed to mind when technology went from EM-SS-DMD. Im not so sure how virtual pinball will go in the future. But Pinball is here to stay. Maintaining machines or getting parts wont be a problem with technology and 3D printing.
One word comes to mind that was coined only a few years ago. MANCAVE!
Every mancave needs a pin!
