This is what getmagic.com started out trying to do. The original getmagic.com was a service you could send an SMS to and their team of people would get it done for you. It was mostly focused on buying things and delivering them to you but I think the idea was that they'd be able to achieve anything, including booking an Uber presumably. It was a bit expensive so they pivoted to serving businesses. I vaguely recall some discussion on HN about it, mostly focused on the 'why' question. There's company in YC23 called Real Magic that I think are having another go.
