Algol is still an integral part of the longest-lived operating system: Unisys' MCP. Sadly, these days it runs under emulation and exists mostly to integrate with external systems running on other OSs. "Sadly" in terms: MCP is notoriously user-hostile - just try it on simH to see it for yourself.
There is an infinite number of universes where Borland launched Turbo Algol in 1983. All we need to do is to find a way to move there. Or, at least, take a look into what happened.
