For vocals...doing 35 takes is simply not good for the voice. If I have 3-5 really good takes, but I need to comp a word or phrase from one take to another...well, that's really not the *computer* fixing it.
If there is a note or two note slightly off pitch...that's not about getting something *wrong* and that you need to keep practicing it.
However, if the vocals are off key throughout the whole song, and you are using autotune to correct...that's a different thing altogether, and probably does require practice and vocal training.
When it comes to instrument parts...it's not much different. If I lay down 3-5 really good guitar leads...but happened to like one or two licks from one take and a couple from another take...comping them into one track isn't about the computer doing it for me...they are still MY guitar parts and my playing. Also...if I hit a string a bit too aggressively on a couple of notes, and it goes a tad sharp in a couple of spots...that also has nothing to do with needing to practice and do another 30 takes. The simple/smart solution is to just pitch-correct those one or two notes...and move on, since overall the guitar takes are all good.
This is is not about fabricating something that is not "real"...it's about polishing off some of the small quirks...which is done ALL THE TIME in studios. I agree that sometimes a great but not perfect performance can sound more interesting with the quirks...but it really depends on the performance and the song. One sour note in an otherwise great performance doesn't always sound "real"...it just sounds sour, and why torture yourself or the talent over one note if you can easily tweak it...and move on.
Does that bother you?
Do you feel like "home recording" should only go to the level of a couple of mics in some makeshift basement "studio" next to the washer & dryer and furnace.
Hey...you only live once....unless you're James Bond!
Some people will spend thousands on a 2-week vacation in some beach resort....me, I prefer to buy a some audio gear and spend those same two weeks in my
home recording studio. Also...some of us have been at it for many years...and gear just accumulates and studio space grows.
