Maybe people got used to computers being unreliable and unpredictable as the UIs we shipped became more distracting, less learnable, always shifting and hiding information, popping up suggestions and displaying non-deterministic-seeming behavior. We trained users to treat their devices like unruly animals that they can never quite trust. So now the idea of a machine that embodies a more clever (but still unreliable) animal to wrangle sounds like a clear upgrade.
But as someone who's spent an inordinate amount of time tweaking and tuning his computing environment to prune out flakey components and fine-tune bindings and navigation, the idea of integrating a tool into my workflow that does amazing things but fails utterly even 1% of the time sounds like a nightmare, a sort of perpetual torture of low-grade anxiety.
