BOOM! It all makes sense. The Internet crowds apparently converged on a game. Now, I have to wonder if she enforces anything in the game or it "enforces" a player decision they don't like. Also, there might be a scenario involving her that people think is "bullshit."
Considering 12 million copies of Fallout 4 sold in the first 24 hours of launch, it's quite possible (if sad) that there's users of Google that know of the game than know of Ada Lovelace (beyond having just heard the name once) or the Ada language.
Keep in mind what data this is drawing from - it's not what people know about, it's what they google.
As such it's probably better considered as a measure of how often people aren't familiar with something, but suddenly find themselves wanting to more about it. It's not too surprising that that happens more for a popular video game or a regulatory law than for a historical figure or a programming language.
