It’s not much different from any day in a life of a bitcoiner who is on the bitcoin standard I would imagine. Your prices keep falling. Software is ever more cheaper to run. You’ll still be paying for material goods, hardware, services etc… as long as someone is providing value, you’ll be paying for it.

I don’t know what an all out AI based society looks like - I don’t think anyone does, but if it is not manipulated and abused, it sounds like everyone is going to have a good time. You’ll have more choice in what you want to do for a living because survival won’t be as difficult. You could choose where to provide value depending on the demands of that market - for example you might still want a human lifeguard on duty or a human baby sitter … etc.
