When a construction guy messes up measurements and thousands of dollars of work has the be removed and redone, no one thinks of taking the employee to court. Why would you want to take your Ai to court?
In your example the owners will often take the construction company or small business owner to court. Most trades people negotiate and redo the work for free or much reduced cost to avoid this.
In office settings if you expose PII you will likely be fired.
We were talking about people sueing AI for mistakes.
Employees do not get sued by their employer for mistakes. If your employer wants you to dig a foundation per plan, and you measure it wrong and dig it in the wrong orientation on the lot, you might get fired, but you will not pay the $50k+ to rip out the cement and put a new foundation.
(Not only that, employees who got a reprimand too heavy handed can sue back. Plenty of cases around.)
"AI" company provides a service. They might or might not be adequate, that's not the point, the point is that the ability to sue them must always be on the cards if the agreed upon terms aren't met.
