For a time, Java was set to be the 'everything everywhere' language, IIRC in some quarters the hype behind Java on everything was even bigger than Cloud, then Crypto, then AI.

I remember those days well. I had the misfortune of working for one of Java's biggest advocates at Sun, Patrick Naughton https://en.wikipedia.org/wiki/Patrick_Naughton

To this day, I refuse to use Java or anything on the Java ecosystem, like Clojure, or Groovy, etc.

I've always thought of Java programming as being kind of perverse with the patterns and verbosity, now I see where the perversion is coming from.

Just you watch, WASI is gonna be next

It kind of was, I remember my "pre-smart" Sony phones having Java games.

SIM cards and secure elements still use this, but it's arguably less Java than Javascript. Except that the trademark and tech (JavaCard) was owned by Sun, now Oracle. It's the basis of the claim, that gazillion devices run Java.

JavaCard is a massively trimmed down version which is more a dumbed down C (with no standardization, little documentation and no third-party tool support) which is essentially Java reduced to basic arithmetic operator, an arguably saner, much trimmed down standard library focusing on cryptography and most importantly no GC.
