If it follows the progression of other disruptive technologies (like the internet, cellphones, bitcoin) there will be a fad/boom period where sexbots start getting a lot of hype, then followed by a bust or die down period where all the manufacturers of the dolls go out of business. Then like 10 years later some new companies will come out with something substantially better and more realistic than anything before, and then that's the one that really makes a massive impact.
It could take a good 20 years or more for sex bots to get good and become a legit alternative to biofoids.
