No, it's actually established in the development of computer games and computer science. AI programmer is a role on a team, just like graphics programmer, systems designer, game designer, etc. Do you have experience in the games industry?
Apparently you have none.
Otherwise you would know that real programmers don't spend their time arguing about the name of stuff and rather just get their work done.
When you look up the credits of Dark Souls, you will find that everybody was just listed as Programmer. That is because programming the enemy behaviour is exactly the same shit as everything else. You just need to be smart enough.
When you look up the credits of Skyrim, you will find that they actually list 3 chucklefucks as their AI programmer.
While Dark Souls was just fine, the "AI" in Skyrim was a pile of garbage. The game only sold because graphics + marketing.
In other words, the developers of DS actually got work done. The developers of Skyrim pretended to have gotten work done by giving their programmers fancy titles.
Consequently AI programming is just a marketing ploy, Q.E.D.
