Many of the Chinese companies are doing very impressive open-loop sim2real. They make great demonstrations. They are not great at dealing with the real world and unpredictable environments.

(That's not true of all Chinese companies - some are doing really impressive work with closed loop systems in unpredictable environments. But many of the highly viewed ones with coordinated dance performances or martial arts are intended more as theater to government financial sponsors than useful function. The technically impressive performances do not look as visually impressive.)
