If the cost of labor plummets I wonder if it will accelerate the timeline for AI, automation, and robotics.

I gave this a shot at home a month ago by cutting my kids off from toys online and getting them a 3D printer. They have already printed more toys than the cost of the printer. The only problem is that the printer was manufactured in China.

I don't see that happening. I reason to it this way;

In 2024, $15 BILLION dollars was invested in AI startups, and a record $250 BILLION dollars by established companies (nVidia/Microsoft/Google/Facebook/Apple)

I don't believe that AI making any meaningful progress on the "timeline" will occur just because you throw even more money at it.
