They have been monkeying with search more than usual the last few months. I expect it is more AI integration. Searching "245mm to inches" returns '245 Meters = 9645.67 inch'.
For some reason, searching for conversions can fetch the wrong result for me. But writing the conversion in the search in for Google Chrome (and waiting for the response) is always correct.
Google was the first CLI I ever learnt now that I think about it. A term and then a bunch of switches that would modify the results. A powerful tool that one could master.
The web has changed (even without SEO) but using Google used to be about knowing the invocation for the box. Now it’s about knowing which results to ignore.
