Automation has evolved a huge amount since the 90s, probably more than the mobile.phone has. This sort of device has been common in food factories for quite a while now and is inevitably moving into first high-volume then after refinement canteen kitchens before slowly making its way into the home.
It's a great thing if it does, the food industry is hugely wasteful especially when trying to lower overheads which also lowers quality and healthiness of diets. Multistage processing allows near to raw ingredients to be sourced locally and used as needed thus avoiding the need for chemical preservatives, pre-proceasing and all the transport logistics, added risk, and etc. Cheap food places could go back to the days of getting fresh produce delivered rather than bags of presliced and shaped meal components from a factory - that'd be huge amounts of plastic and oil use removed from our global consumption.
Of course this installed device is probably just fairly basic pick and place using preshaped meal components but it's a step in the evolution of small-scale industrial kitchens which will eventually benefit us all.
Sometimes I day dream about what I'd say if I was elons friend. There are a lot of things.
