I hope early home robotics will be like a game console launch - a community rush to break through any initial barriers to homebrew. Specific early firmwares will be desirable and a whole community will form around creating exploits and running user software. As old robot units fall out of service and are sold in bulk, the community will pick them up and keep them running.
I for one eagerly look forward to alien-autopsy like videos of people reverse engineering robots that they acquired by 'disabling' whatever equivalent of Lime/Bird/Volt service sends out on the streets to do stuff for people.
It'll be neat to walk through some weirdo mechanics shop that's full of robots in different states of disassembly that have been repurposed to help with whatever mad scientist hacker schemes that they have in mind.
