It's a bad criterion for judging something noteworthy.
15 years after whatever this breakthrough is will anything have changed outside of the lab? That remains to be seen, but I'll believe it when we see the data.
The newspapers didn't cover it until random people started asking why the feats they'd seen with their own eyes weren't being written about.

It's a bit like with Elon Musk (re-)inventing the electric car. Those popular names that went down in history are usually not the original inventors. These people were first of all successful entrepreneurs that understood business and ultimately won the patent war. But in the early 20th century, the idea of flight was already firmly established, why would any "respected scientist" have doubted what could already be observed in action around the Western world?
A few years back I read David McCullough's biography of the Wright Brothers which told the same story: https://www.amazon.com/Wright-Brothers-David-McCullough/dp/1...
This site cites a couple of the pre-Wright naysayers: https://bigthink.com/pessimists-archive/air-space-flight-imp...
It certainly sounds like just another Monday to me.
