Well I'm claiming that most future ones will not. There's no reason that smartphone/tablet style OSs couldn't accomodate video editor, graphic designers, writers, salespeople, real estate brokers, etc in the future. And the demand exists, so I'm betting that that'll be our actual future. But they cannot in principle accomodate software developers.
