To me it sounds like a justification for not having access to a great studio. Just fooling ourselves believing that you can create in a 5 thousand dollar home studio records as good as those recorded in proper studios, with a capable enginner and producer.
I have a project studio, and the awful truth is that i wont ever record something even close in quality to a frank sinatra record, henry mancini scores, pink floyd, RATM, Motown, etc. No matters how good i become. It aint gonna happen. And i havent seen someone made it happen.
What will happen if your predictions are wrong and in 10 years kids become tired of sampled and computer based music and go back to the roots? who will be in demand? an enginner who never miked a drum? or an enginner who did it hundreds of times and can learn in a couple of days to use autotune, melodyne, BD, vocalign and whatever new production tehcnique becomes popular?
Where are most of those 80s enginners who just nailed that particular sound right now?
