Yes, I came to make this comment. Toyota has been very vocal about making this change. The rationale from Mr. Toyoda himself was something like:

(1) Robots are not great at improving on their own work in the same way that humans naturally are.

(2) When he was a boy, Mr. Toyoda recalled that there were always a few men around the factory who were capable of extremely creative and ingenious solutions to difficult problems of logistics or fabrication, and he feels that this skill is being lost.

Anyway, this has been a major consideration for the current management at Toyota for some time.
