Anime (and manga) have definitely become more popular in the last several years – In the old days when I was a kid, you really had to go out of your way to get your hands on the original Japanese version. Now most shows are easily accessible as a home media purchase coupled with an English version that sticks close to the story as intended (with the exception of the much more recent political debacles, but that’s another topic).
But I don’t really want it to break into the mainstream. Just look at what happened to video games and western comics – As soon as it started to become more culturally acceptable to like those things, the tone police didn’t fall far behind and before we knew it companies just lined up to fall like domino’s to pander to those people. This ended up bleeding over to the western anime industry eventually. Don’t think they won’t try the same thing on the other side of the Pacific: They’re tireless and are convinced by their own moral superiority.
Anime is better off staying as something relatively niche.
