We've already got realdolls.com if one wants to blow 7k on a sturdy life sized object in the female or male form. That would be useless to me.
Now stick in a chip with custom programable BCD and intelligent conversation and could that be the end of the hobby as we know it?
Suppose you could create the robotic lifelike intelligent provider of your dreams eliminating Ymmv, covered anything, smoke smell (and other unpleasant odors), legal, health and safety risks etc..
In other words keeping all of the good stuff but eliminating all of the bad stuff for let's say 10k would you still hobby?
I hobby in between relationships so I think I probably would make the purchase.
Trading a possible one hour for-hire human connection for 100% consistent top level BCD? Hell yes I would do it but she would have to really be life-like which includes self cleaning.
I would get all of my human connection needs from RW relationships.
I'm willing to bet if given a choice any provider would gladly choose an always loaded ATM machine against the bedroom wall over renting her body out to strangers by the hour.
