The hidden cost of an unreliable assistant: people stop asking

There is a cost to a slow, unreliable assistant that shows up in no benchmark: once checking its work takes longer than doing the task yourself, people quietly stop asking — and stop trusting the brand behind it.

In favour
  • A useful design metric: judge an assistant by how much you have to verify it, not only by its capability scores.
  • Trust is earned by reliability over time, not by announced features.
Worth watching
  • Capability on paper does not equal adoption in practice — a model can top benchmarks and still be routed around.
  • The disengagement is silent; there is no error message that says 'the user gave up'.
Our takeWhether you build assistants or buy them, the question is the same: does it save time, or just move the time into checking it? Verification overhead is the real bill.
