I understand your point, and I kind of agree, but does it really matter? When we enjoy old artifacts we don't have the same experience as someone who did it back in the day. Old paintings will shift colours, old buildings will decay and might become ruins, old books might need to be "translated" due to language shifts, and in any case we lack the proper cultural background to fully appreciate them.

In a few decades everybody who played the PS2 upon release will be dead, and our descendants will not care if the emulation is 100% accurate or just 99% accurate.
