decades of wasted opportunities

if a country receives the opportunity to use androids for jobs, then what are the advantages?

the most obvious reason is that androids protect themselves and needs no security arrangements at all.

even if a country does not have access to exotic technology or only has limited access to primitive technology, androids have access to exotic technology to protect themselves among other things.

usually if not always, androids work alone or androids work with other androids.

if humans tries to help androids in any way, then that increases the risk against androids.
