Does The So-called Law Of Diminishing Returns Apply To Knowledge

Take the new Russian Tests of supersonic intercontinental missiles for instance.It appears to me that this is a recycling of old technology sensationalised.

Rocket science is as old as Adam and Eve and all the testing was done decades ago in the modern world.The cold war of the 60's and 70's only produced fear of what might be.Now in 2021 Putin desperate for publicity has played the old card of brinkmanship once again.

No matter what area of knowledge we can look at there is nothing genuinely new.For instance TV's, Washing Machines and Fridges and Cars are the same old technologies with some more bells and whistles.Electric cars are a known technology that has been politicised.

Medical Science I Think is nearing the "point of diminishing returns" for effort.There is still medical breakthroughs but mostly because mega amounts of money is now put into research.Gobsmacking medical breakthroughs are also probably a thing of the past.Slow and steady progress based on well known science are now the norm as I see it.

Those golden eras of Einstein and Newton and later on the developement of things such as heart lung machines and organ transplants are now a part of everyday life.

Genuine new knowledge is in my opinion now "running on empty" and those wonderful era's of discovery now take pride of place in prestigeous science museums around the world.

When was the last great painter in the league of Picasso for instance or truly great world acclaimed singer- song writers like Lennon and Mccartney.The Era of the great Opera singers that thrilled packed audiences around the world has as far as I can make out come and gone.Our great actors and actresses now are either in the twilight of their careers or have moved on.

To sum this up I Think that we are embarking on an era of mediocrity that will last for at least decades and more likely for centuries to come.
