I don't see how that's a possible forseeable case, even if there is no such thing as a "personal computer" any more: tablets still have SSH software, and "tinkerer-level" cloud VM instances will still exist and cost no more than $5/mo.
On top of that, each app lives in its own context and can hardly be "pipelined" with other apps to achieve something creative. It's the death of creative computing.
Even as a web developer, it boggles the mind to understand why browser context menus have "View Source" on by default, rather than a developer mode switch. This sort of stuff hits me hard. Like dead pause/break keys on laptops, wireless switches on the chassis. Nobody is actually paying attention to what they're building.
So you are at someone else's mercy how much and what to tinker with.
