I see folks building bedrock-type abstractions more and more these days and adding on @tbsp's list, I tried to gather every single virtual machine designed explicitly to fend of bitrot or digital obsolesce by targeting a frozen specification I could think of. I was wondering, I'm sure I must have forgotten some, if you can think of one that is not on the list, could you please let me know! wiki.xxiivv.com

Why Rust is different, with Alice Ryhl

Their words
Now the thing is you can of course write examples in your documentation and Rust makes all examples into tests. This means that if you change the underlying code now your test fails. And so this means that you can't even you can't forget to update your examples in your documentation.

TypeScript
Their words
My opinion is that the least mature area is front end. There have been some attempts to compile Rust to Web Assembly and then run it on the web as a front end as a replacement for TypeScript. But if I was writing a web server, I would totally use Rust for the back end and TypeScript for the front end. I would not really go the web assembly route.

Why Rust is different, with Alice Ryhl youtube.com
Their words
I think this is kind of leads to another way that Rust really helps with reliability, which is that if you're refactoring, I think Rust is really good at telling you all the places you need to update. I've done this sometimes where I would refactor something. I change the code. I change the return type or whatever it is, and then I just fix the compiler errors and until the compiler stops shouting. And then once I've done that, I've updated every place I need to update.
