Factory robots are incredibly graceful now and sensor systems are great at combining information into models, I would say that they're almost certainly able to act safely - they're not going to stab anyone by mistake, but might occasionally call for help locating a carrot or odd things until those small bugs are ironed out.

I think fully multitasking robots are a way off because like self-drive there's just so much complexity caused by small differences that accounting for it is endless, but an arm on a cooker with a prep area beside it would be restrained enough that solving the individual design issues would be manageable.

I should say I'm not imagining it to be as good as the advert, the first ones will have fairly basic ingredients and dishes they support - probably a few thousand but missing various key dishes that are a bit too awkward. I'm Also imagining it'll cook better than me but not upto my mums best.

So I don't think they'll replace chef but we're about to see a slew of task focused devices, probably in construction and similar fields. The chef focusing on the more creative and skilled elements while using them to chop, stir, make sauces or icing or whatever.
