I agree with most of this, which is why emulation is generally better unless you specifically want to operate/show off a museum.

Maybe things will be like the Nintendo BS-X where people will reverse engineer consoles with games downloaded to extract the game from it.

That being said I do have a physical Atari 2600 with a few games. Astroblast with paddles is still a fun game today, and Video Olympics (the Atari VCS version of Pong) is extremely fun to bring out at parties.
