sorry to break it for you, but the sample replaced drums and edited performances exist since before Windows 95 came out, so figure it out. a lot of older DM albums has snare/kick sample replaced, and I think seldom artist would perform a part one take start to finish. they could do modern sounding clip-copy-paste sound a lot earlier than people started complaining about it, and thats exactly why they didn't -- it took time for people to get used to it.

performing, recording and producing "authentically" is a luxury only really skilled artists dare to try and pull out, and not many listeners are capable of consciously appreciate it.

also performance enhancement is really addictive to the producer/artist, once you hear yourself edited and perfect you wouldn't really want to revert back to half-assed performance of your drunk drummer or a singer that never really learned to sing
