Because every principle investigator in academia works in sales.

Some tried to hold out and keep calling it "ML" or just "neural networks" but eventually their colleagues start asking them why they aren't doing any AI research like the other people they read about. For a while some would say "I just say AI for the grant proposals", but it's hard to avoid buzzwords when you're writing it 3 times a day I guess.

Although note that the paper doesn't say "AI". The buzzword there is "anomaly detection" which is even weirder: somehow in collider physics it's now the preferred word for "autoencoder", even though the experiments have always thrown out 99.998% of their data with "classical" algorithms.
