Yep, one of the example in the Wiki is robots building robots since 2001:
"FANUC, a Japanese robotics company, has been operating as a lights-out factory since 2001.[6] Robots are building other robots at a rate of about 50 per 24-hour shift and can run unsupervised for as long as 30 days at a time."
With IIOT (industry internet of things) that definitely seems like a possible reality. However, as long as Skynet is controlled by ex-factory workers it will be a promotion for everyone.
