Yes science is going backwards. IMHO, science is being repressed for political reasons
I feel that some political person has looked into the future and seen that the need for scientific people is very small. Science jobs can be high paying and high status jobs. This means that these types of jobs must be reserved for the members of the elite. Their sons and daughters and their chosen lackeys.
In Britian, the country is closing hard science departments in many colleges. It is something of a scandal amongst the academics in Britain. They feel they are giving away any possibility of British leadership in the sciences.
Simultaneously, science has been the victim of a silent PR campaign or perhaps the absence of a PR campaign. In the 50's and 60's and 70's, being a scientific person was a respected role to play in society. The TV and society in general talked about the space scientist and the defense engineers making missiles or nuclear naval vessels, etc. Today, science people are depicted as people with social or psychological problems. Unable to mesh in normal society, they take refuge in science. They are ignored until needed to solve a problem. Once the problem is fixed they recede into the background again to be ignored again.
What young person is going to go thru the necessary work to be a scientist only to be rewarded with derision or disrespect from the majority of the members of society? Today's society shows children that if they are singers or dancers or actors, or sports stars, then they will be popular, have money, be normal.
Another political reason is power. Science is power. If you look into military tactics, you would be chilled to discover that educated people are targets. They are the people who rebuild the society during and after war. Therefore they must die. You can see this in action right this minute in Iraq. In Iraq there has been a campaign of murders of scientists and academics across the country. If the death squads responsible can kill or force into exile all educated Iraqis, the remaining uneducated people will be an easy to control captive populace. They need the conquerers to rebuild the country because all the native intelligent people have been murdered or frightened out of the country.
The government, beginning around the Reagan era, began to actively repress knowledge that is available. When I was younger, I could go to the library and check out books on rocket propulsion, rocket nozzle design, chemical explosive formulas, drug formulas...just about anything you could think of. Now if you go to the library, it will probably be closed. If it is open, the book selection is miniscule. If the book selection is large, there will be large and obvious gaps in the knowledge that is available.
I can think of some research that was supressed for purely political reasons. There was a study done to determine the genetics of Isrealis, Palestinians and other Arabs I think it was. The report showed that Israelis were about 96 percent or maybe higher genetically similar to Arab or Palestinian people. This would not serve the goals of Israeli politics so the report was supressed.
It is almost always in the political interest to repress scientific innovation. Ben Bova wrote a great book about e books. This was before e books were mainstream. His book focused on the idea that e books would destroy the lumber, paper mill and publishing industries. Therefore, these industries would do anything to stop the scientific innovation of e books. No matter how helpful the technology was to society or the environment. The only thing important was profits and the possible political fallout of people losing their jobs taking their frustration out on the politicians currently in office.
