Maybe Steve Jobs' greatest accomplishment was getting titans like Jony Ive and Steve Forstall, who could each run their own successful design and/or tech companies, to put aside ego and work together under one roof.
Yup. “My model for business is The Beatles. They were four guys who kept each other kind of negative tendencies in check. They balanced each other and the total was greater than the sum of the parts. That's how I see business: great things in business are never done by one person, they're done by a team of people.”
Bands are hard. People in bands are passionate, often drunk and/or on drugs, almost guaranteed to be egotistical, and fiercely competitive - not at all team players by default, more like literal 10X music rock stars. (It doesn't help if they are.)
There's almost never a supervising manager to keep it all together. (Producers are temporary, and band managers are more like salespeople and hired negotiators than corporate managers.)
It's interesting to wonder what would happen if you took difficult but talented musicians and somehow managed them into smooth cooperation. Maybe Jobs did indeed do the software and design talent equivalent - but even he would have struggled with getting to happen in the music business.
