This is the beginning of the end for many of them too. Look at the opening line of the page:

> We’re teaching AI to understand and simulate the physical world in motion, with the goal of training models that help people solve problems that require real-world interaction.

Text-to-video is just the flashy demo that everyone can understand after exposure to text-to-image. Once the model can "simulate the physical world in motion" it's only a few steps away from generic robotic control software that can automate a ton of processes that were impossible before.

Humans still have the benefit of dexterity and precise muscle control but in the vast majority of cases robots can overcome those limitations with better control software and specialized robotic end effectors. This won't soon replace someone crawling under a house or welding in awkward positions, but it could for example replace someone who flips burgers or does manual labwork.

This could eliminate the limiting factor for automating many manual processes. (ruh-roh)
