I really enjoyed the text.

From the perspective of a python programmer it all seems valid.

A Java-Dev would probably write the same about an embedded engineer.

As embedded dev, the stack trace alone scares me. It would be funny to watch the Java runtime blow the 8 frame deep stack on a PIC18 tho

Honestly, I prefer C to Java, it's incredibly simple without all the BS that Java throws at you:

interfaces - compiler will fail if you provide the wrong types; w/ Java, figuring out what types to pass is an effort unto itself
functions - everything needs to be in a class; even callback functions are wrapped in a class (behind the scenes if you use modern Java); in C, you just pass a function
performance - Java uses a stop the world GC, which can cause issues if you have enough data churn; in C, you decide when/if you want to allocate or free memory, no surprises

There are certainly some bad parts, but all in all, when I run into an issue in C, I know it's my fault, whereas in Java, there are a million reasons why my assumptions could be considered valid, and I have to dig around the docs to find that one sentence that tells me where I went wrong w/ the stuff I chose.

That said, I prefer Rust to both because:

get fancy stack traces like I do in Java (I really miss stack traces in C)
compiler catches most of my stupid mistakes, Java will just throw exceptions
still no stupid interface hell, I just satisfy a specific trait and we're good
generally pretty concise for what it is; I can rarely point to a piece of syntax and say it's unnecessary

I use:

Python - scripting and small projects
Rust - serious projects or things that need to be fast
Go - relatively simple IO-heavy projects that need to be pretty fast
C - embedded stuff where I don't want to mess w/ the Rust toolchain

Java has been absent from my toolbox for well over a decade, and I actively avoid it to this day because it causes me to break out in hives.

Sorry, you had a small error in the spacings of your post; Therefore I cannot parse a thing you're saying. Didn't mean to scare you with a semicolon either. It's just a tool in language's to end a clause and begin a related, independent clause. That could be useful somewhere...
