To be fair, can you pop a PS1/PS2/PS3 disc in a PS4 and play it?

You can pop a 360 disc in the one and play it, soon perhaps also certain original xbox discs.
You can pop ps1 and ps2 discs in an original ps3 and play it.
You can pop a GC disc in a Wii and play it.
You can pop a Wii disc in a WiiU and play it.

You will never be able to pop a disc in the Switch, nor a 3ds cartridge btw.

By the same token though you can put a DS cart in a 3DS, a GBA cart in a DS, a GB cart in a GBA.
