Perhaps Push Button just has an extremely buggy A.I., much like Artoo Detoo in Star Wars (
"For a mechanic you do an excessive amount of thinking.") This is why Droids in Star Wars are meant to routinely have their
memory wiped, to prevent the droid from developing personality and independence that might override their programming leading them to act against the wishes of their owners (although in the case of Artoo, his lack of memory erasure proved beneficial, but in other cases it proved detrimental, such as in the case of IG-88A whom some might argue became nearly sentient). David in A.I. also developed his own quasi-personality and independence -- although he never did really deviate from his original programming (i.e. to eternally obsessively seek his mother as a simulation of love).
If an artificial intelligence were to become sentient/sapient, this would also raise a whole host of ethical/moral questions - which is most likely why Star Wars Droids are routinely memory wiped. Namely, would that artificially intelligent and now sapient entity be entitled to
rights as other sapient beings? This is a question that Isaac Asimov explored in "The Positronic Man" (adapted into the film "The Bicentennial Man") and "I, Robot." In Star Wars, if a Droid were to become sentient/sapient, then continuing to treat them as property would become slavery. While slavery does exist in the Star Wars universe, it's generally abhorred by the "good" characters, yet nobody cares about the 'enslavement' of Droids. Our hero Luke Skywalker and his family happily owned and purchased Droids to work on their farm, and installed
restraining bolts to prevent them from fleeing (Artoo was able to bugger off to find Obi-Wan Kenobi because he deceived Luke into removing his bolt - again, part of the higher level A.I. shown by this Droid due to his lack of memory erasure).
But I would argue that despite everything that Artoo's been through, while he may be sentient, I don't think he's sapient. Artoo's the one character that's witnessed the entire saga from beginning to end - from when Anakin was slave boy to his rise as a Jedi to his fall as a Sith. If he were sapient, surely he would've figured some things out and mentioned it to Luke! ("Dude, I think Vader's your father, cos check this out...")
