I know im a big nerd but "Musk also presented the Optimus robot, your plastic pal who’s fun to be with — “your own personal R2-D2, C-3PO!”.
Why would I need an astromech droid Musk? At least a GNK droid provides power. Stupid sexy gonk droid.
What I really need is a droid who speaks the binary language of moisture vaporators.
Considering the important parts of that, aka the languages can be done by your phone sure. But it would at least have a minimal use. R2 d2 needs special attachments to serve drinks.
The cybertray, competitively priced at 4000$ and the reported risk of it breaking when wet is fairly minimal.
