Anyways, over a decade back, I was watching a recording of a musical artist from either the 70s or 80s, and was surprised at the quality of the presentation (audio, music, harmony within the team) and was thinking on the same lines - good vs good enough, and how this team working in the 70s made musical magic.
I think the constraints those days made the masters really practice practice practice so that they could be great at the spur of the moment. A lot of people today may be more expert in synthesizing music so they can take a second's worth of snippet here, 5 seconds of snippets there, and eventually make something good, but it is all editing and they may not be able to do that live, but the old timey greats had to perform live, and for that they had to be great.
I am not saying no one does live music nowadays, quite the contrary, just saying that a lot of great music comes from people who never do live music, and that is because they can afford the luxury of 'editing' (which is kinda similar to divided attention span). Similarly, for the baker once the bread has gone bad there is nothing they can do but to start over, and that would be the incentive to get everything right.
