I work in the finance sector, and I don't see any new projects being built around JVM (or kafka, or cassandra, but elastic search is still popular). That said, the existing java product deployments are solid and there is no terrifying rush port them. New web tooling is a split between go and python. Also it doesn't hurt that gigantic amounts of business logic are PLSQL, with more going that way every day.
We haven't seen .NET for a new project in 5+ years. Doesn't mean it's not a viable tool, but the deployment story is a cost nightmare to us, and our teams distrust the upstream vendor.
Tons of stuff is still built on the JVM. The big five tech companies (besides MS) use Java nearly exclusively for back end development. Python is good for ML and data crunching, but compared to Java it's dog slow.
Go is definitely catching on but nowhere near passing Java, maybe it will someday
