So, as of the shutdown, is there anything even close to a usable software stack, or is it all just prototype stuff?

Why, if they had all that funding, and assuming that they had good reasons for a custom OS, would they fail to hire an experienced team to build one -- it seems that the time saved by experience would be well worth it?

Bottom line, is there any software of value that some other drone company might want to purchase?

(edit: add last line)
