Sex doll? No. Blowjob machine? You betcha. It's been interesting watching how fast the tech has been developing on this niche over the last few years. We've gone from that shitty noisy AutoBlow thing to some serious pieces of Chinese tech that suck and move 12 different ways, heat themselves, and are easy to clean up afterwards.
Until the tech gets as good as it gets in the movie Ex Machina, and it won't before I'm dead, I'm pretty sure, I have no interest in a sex doll. Can't get past the uncanny valley with them.
