Even if the sex bot costs 15k like mentioned above, its "pay once" and all the sex you want. Think long term
if the hobbyist spends 300 a week on providers (once a week) then in 52 weeks he has spent more than that bot will cost. And the BOT will have a warranty like a car most likely.
Now it will need to be recharged so it will be lifelike else you need extension cords. and in a power outage well, its a dead fuck.
Personally I like the real thing because with a bot you have to install updated software and all it takes is one malware infection and the next time you DT the bot it performs a Lorena Bobbit on you
