Google no longer shows any search results for some searches, only infobox

I get results, so Im guessing its a test not a "No longer shows"

The slow creep of Google centralization is working less in their favor than I believe they understand.

I like the “Answered in 0.15 seconds” instead of “About X results (0.27 seconds)”

Kind of feels like a similar experience to asking Alexa a question, except with Alexa it's as if you always got the infobox or the "i'm feeling lucky" result.

I find this a remarkable change. Has Google or any other search engine ever done anything like this? This is what I see in case others see differently. https://imgur.com/a/ttvRY

Can't see any search results at all on the search results page.

...until you press the button.

(I see a "show all results" button.)

No doubt Google will accept ads from sites that were previously listed. Nice racket they got

There is a "show all results" button immediately below the stated time.
