Like LLMs, though: Do you really think a simulation will get them to all the corner cases robots/AI needs to know about, or will it be largely the same problem -- they'll be just good enough to fool the engineers and make the business ops drool and they'll be put into production and suddenly we'll see in a year or two stories about robots crushing peoples hands, stepping in drains and falling over or falling off roofs cause of some bizarre miscommunication between training and reality.

So, like, it's very important to understand the lineage of training and not just the "this is it"
