This is exactly the point.

There was a fifteen year period where the best way of finding out what something meant in a programming language was to Google it. Pre-AI, post the predominance of newsgroups and offline documentation.

Try googling "$|++". It just doesn't work. Never has.

Now Google "file.flush". First hit is the answer you need on SO.

You did not need to google anything. The complete documentation was right there, next to the interpreter, on your machine. Ready for scanning and reading from top to bottom; and broken in sections that were actually relevant; and ready to search in bulk if you prefered with whichever local search tool you cared for.

No need for google. (And google was run by python fans; probably saw no need to support searching for '$|++'.)
