...Why do these lazy people put so much effort into coming up with fancy words to justify that laziness?

That's a really good question. Maybe it's because laziness is associated with a lack of intellect? And certain technologies, like AI and other software, are meant to augment our intellect.

These fancy words carry an intellectual/productive effect. When they're put to use it probably makes people feel like they're getting things done. And they never feel lazy because of this.
