That's a very valid point.
Well, we have gone mostly digital over the last decade so most kids born or growing up in this time period wouldn't really know. It's just like if you ask me about Atari consoles, I couldn't tell you anything because I never grew up playing them. In addition to that, most older games can be played through emulators so there's no real incentive for kids nowadays to know what the cartridge of old gen consoles look like. It is sad but one of the side effects of the evolution of gaming.
