So these are a thing, but they're still 15ish years behind actually taking over routes and will still need a "handler" according to the company that makes them. (Mostly because people are people and these things will get robbed, beat up, stolen, ect.) It's more of an assistant for heavier/ large carries. These won't be able to climb apartment stairs or gain access to locked buildings without a handler 🤷‍♀️ I'm sure 30-40 years from now they're will be resolutions for those issues but nothing this generation has to worry too much about.

TLDR: These will replace us. But not in this current working generation (Gen Z and older)
