Might be easy, and I imagine they are going to shuffle employees around (they read HN) believe it or not, they are humans and make mistakes. It's very likely that up to this point in time, they didn't think to use ML on proposed ads, and even if they did, it's not like every employee working at Google has ML skills yet. The most advanced ML departments there are probably already working on their top priority issues that need ML. Second tier ML guys at Google are probably the ones that are learning ML just like many devs on HN, won't quite have the expertise to get this stuff moving quickly.

But yes, if they wanted to, they can divert their more advanced ML teams to tackle specific issues like this first and get it done. I really doubt this is a high priority issue for them.
