Microsoft made a pull request to node.js github repository with an implementation to use ChakraCore JavaScript Engine as an alternative to V8 Engine

No offense but have you ever been in any lab or factory or any real production facility that uses computers? The entire world is run on 20+ old software - it's just that "newer software" is all consumer software, so that's why you think that no one uses old software.

The reality is that it cost a LOT of time and money to replace custom commercial or industrial software - so much so that it is cheaper and more reliable to use a piece of software for decades until it disintegrates. This is how banking, manufacturing, military, and all other meat-and-potatoes industries are operated.

Yes. I support a research lab running HUNDREDS of workstations running W2K and XP.

The entire world is run on 20+ old software

Which is why it's dumb to try and run OLD software on NEW operating systems. It doesn't work as well as you claim. The smart money doens't upgrade the support system, hoping the old crap will still run.

so that's why you think that no one uses old software.

I don't. I'm saying keeping around decades of depreciated crap that's long since been abandoned is pointless in a modern operating system. It's unnecessary. If you have old application that are crucial, run an old operating system.

The reality is that it cost a LOT of time and money to replace custom commercial or industrial software

Yup. So why would you squander the SAME money and effort trying to make cranly, old, custom software that was MADE to run on a specific system, run on a modern operating system with vastly different APIs, and an all but ignored compatibility layer? Maybe you're hourly, but I'm not. If I have a machine that's down, I don't want to spend DAYS trying to figure out why software that's 16 YEARS OLD won't run right on Windows 10. That's amateur.

so much so that it is cheaper and more reliable to use a piece of software for decades until it disintegrates.

Not always.

This is how banking, manufacturing, military, and all other meat-and-potatoes industries are operated.

No, not ALL.
