Can robots become enlightened?
Lol why would you program ego into a robot?
Of course, if you do that, that is, if you program self-defeating, completely irrational behavior into a robot, along with the means to self-correct and eradicate that behavior, then yes, a robot can become enlightened by definition!
If you don’t program a way to eradicate this behavior, then this behavior is what you wanted from a robot, by definition also, so it’s already enlightened!
Lol.
