PKD stories and novels frequently feature autonomous or semi-autonomous machines. Joe Chip, in Ubik, is refused service by his apartment door, and later, an autonomous diner service, because he is broke. Also, Dick would use the early '90s as 'the future' pretty frequently.
It makes sense given that straddling the line between what is real and what is fake is perhaps the most persistent theme in his works, and this persistent chipping away at the agency of humans by robots by bureaucratic enforcement of rules is also all over his works. Of course then with the regular nagging doubt about who are the humans and who are the robots.
