I don't know... Watching the array of Apple OS'es (OSX , iOS, WatchOS) during the WWDC keynote, I got the sense that this has got to be a maintenance nightmare. Microsoft seems to be aiming another direction with the one Windows theme--although the thought of making that work also makes me cringe. I'm out of touch with modern development, but simple seems to me to be the best policy.
Is anybody out there more in touch with the details--Is there enough significant overlap that keeping the ecosystem in sync with itself seems to be a reasonable task?
If that is Paul's belief system, he sold it out awfully quickly because he was "fascinated by one class lab". He is now "astonished that the daily grind of depriving, shocking and killing these animals did not move me to leave my job." He quit because he lost interest and wanted to be a programmer, stealing a lab coat in the process...
I don't mean to be too harsh, but the thing that comes through loudest to me is that, by his own measure, Paul may be a bad person.
