Boulder isn't a fan of human computers.
He doesn't understand why they have to be so complicated when all humans want to search up is how to find something or when they feel a certain way, not to memtion the whole build of it was a question of his own.
Sure, he like engineering and all things related to it, but those computers were like Unicron to the bot. He still remembers finding out about Siri and she was the worst thing he could ever talk to in his life.
Seeing Vigil for the first time, it only made him think that the worst was yet to come with this thing. Although all the bots said it would be fine, they had been clearly proven wrong.
To this day, any out of control tech that was extremely terrible and definietly of that to attract hatred, it was to be called Unicron. Yet, as Boulder said it aloud once, Cody thought he said Unicorn.
Now they just call bad tech Unicron the Unicorn.
