maybe? maybe not? I think part of the equation is the style of music you are creating... but that's another thread<G>!
Here's what I do (advice valued at exactly what you paid for it!)... my background includes a couple of decades of editing tape with a razor blade, spot erasing, and manually riding the faders. So I pick and choose my editing tools based on one simple rule - if I could have, or would have made an edit back when my tools were rudimentary I will make it now. Otherwise, if the problem genuinely takes away from the track I'll find another way to fix it.
Same goes for processing... I used filters and dynamics processors then, and I use them now. I use them differently - now I can 'afford' to have a compressor or equalizer on many more tracks than I could have ever afforded then.
Which is not to say I don't take advantage of the tools available to me!
I LOVE being able to undo an edit if I goof it up - WAY easier than putting a sliver of tape back!
I am getting better at using tools like AudioSnap to conform sequenced tracks to tracks played live. While this was never necessary when it was tape only, it can add a great deal of life and realism to sequenced tracks.
Every once in a while I will record a track that is just amazing, a great, if imperfect, performance. At which point Melodyne or Auto-Tune can minimize the offensive moments, and rescue an otherwise great track.
The other thing - tools like Melodyne, lots of compressors or delays, etc can be used as sound design tools, the likes of which we never dreamed of in 1977!
