And Facebook has written a transpiler to C++, then a new language based on PHP, and a VM for it. Seems like quite an investment.

To over-simplify, Google probably just tunes the Hotspot JVM.

Uh. Google reimplemented all of java for Android. And then invented a whole new language to replace their internal use of C.

And now, of course, dart and flutter, on a new OS to replace the Linux underpinnings.

Would they pass up booking.com solely because it's Perl? The value there hasn't much to do with the plumbing.

Php today bears little resemblance to the performance drag it was years ago.

I’d wager they’d take a closer look these days.

That said, there is a lot of poorly written legacy php code out there before frameworks really took off for that language.

Most PCs are doing fine with Windows.

Because Windows isn't bad
