Washing machines are robots, but they’re not intelligent. They don’t know what water or clothes are. Moreover, they’re not general purpose even in the narrow domain of washing - you can’t put dishes in a washing machine, nor clothes in a dishwasher (or rather, you can, but you won’t get the result you want).
They’re just another kind of automation, no different conceptually to a conveyor belt or a pick-and-place machine.
Equally, machine learning lets us solve classes of problem that computers could not usefully address before, but each of those problems will require a different implementation, and different data, a different route to market, and often a different company.
Each of them is a piece of automation. Each of them is a washing machine.
