WWII and the Cold War exacerbated competition between the great powers, which led to unprecedented investments in scientific research (only one lunar program took about 5% of American GDP). The Internet, computer, nuclear technology and cryptographic algorithms were developed for the needs of the military-industrial complex, then smoothly seeping into the civilian sphere. But the Cold War is over, and fundamental research has become unnecessary for the powerful. Nobel laureate in physics Andrey Geim states:

There is a deep crisis in the production of new knowledge. Not that discoveries were not made at all, but the number of them decreased significantly. But without new knowledge, only derivative technologies may appear, and they, no matter how important they are, are not able to maintain the level of economic growth to which the world managed to get used to after the start of the industrial revolution.

Most of the phenomena and processes usually have a simple explanation.

Over the past 2 centuries, we have observed 3 technological breakthroughs: the middle of the XIX century, 1950-1970 and 1990-2010. All are not due to a sharp increase in the population within one technological zone (market).

In the middle of the nineteenth century, Great Britain was able to dramatically increase labor resources thanks to colonial policy.

In 1945, to the most powerful leading countries of Europe and Japan joined the American economy.

In the late 1970s, China and other Southeast Asian countries entered this zone.

A significant increase in the number of workers led to an increase in the degree of division labor, reducing costs, increasing labor productivity, accelerating scientific and technological progress.

Currently, the possibilities of expanding the American economic zone are very limited.

It seems to me that you are a little mistaken, and right now there is a powerful breakthrough, and such that everything is changing literally before our eyes. In my opinion, the XXI century, like the XIX, will be the century of CHANGE. It was precisely the 20th century that already existing discoveries and inventions were improved for the most part. I will try to explain. If a person at the beginning of the 19th century saw the end of the same century, he would have precipitated. But a person at the beginning of the 20th century would have been more or less ready if he had looked, say, at 1995. There were already cars; aircraft - assumed; video (in the form of a movie) - it was; telephones - were; electrical appliances - the process has started. But if he saw 2018, he could already be hung up with surprise: phones without wires, combining a camera, video camera, voice recorder, radio, gramophone, calculator, computer, TV, book, notebook, radar, wallet, etc. .d. etc. - from this, a person from 1950 would have been delighted (yes, even at the beginning of the 2000s, in addition to talking and SMS, almost the main entertainment was to disassemble / assemble). IMHO, just from the second half of the 1990s a powerful breakthrough was made, and continues its development.
