> Java solved it with a JAR file

JARs still require a JRE to run, and the runtime needs to be invoked. The equivalent would probably be a Python zipapp (which are just Python files zipped into a .pyz the interpreter can run).

Static binaries are one advantage that languages like Go and Rust have though, yeah.

You can bundle a JRE with a JAR to get a self contained executable.

Also don’t forget that many compiled languages depend on a particular libc so you’re not totally in the clear there.

A JRE + binary deployment weights in over 100 MB.

An ordinary compiled binary would be a fraction of that size, saving you time in provisioning and deployment.

Small price to pay if you have a JVM team already.

Most programmers (HN is a bubble) hate learning new languages.
