I don't know if those industries have died, but certainly both have fallen prey to intense politicism. It is difficult to gain consensus on science when there are cottage industries on both sides determined to deny such consensus when there are policy implications.
Meanwhile, the scientific community continues to work towards consensus on a wide range of issues that do not have policy implications. It rarely achieves that consensus, but over time certain theories are confirmed to be true and others are tossed aside.
The politicization of a specific scientific issue is something that has happened over and over again and so often you'd think people had learned their lesson to NOT allow it to happen. And when those who have become politically invested in some theory are in positions of power, they demand it be the basis of LAW. Which invariably ends up harming people and even be responsible for the mass murder of people. Politicizing science has happened several times and not just in this country -the most notable examples occurred in Nazi Germany and the Soviet Union.
The politicization of some scientific theory in order to exploit it for political gain and increase their base of power is ALWAYS -as in ALWAYS -done by the left. (And don't bother with the creationism bullshit -that is in response to the politicization of the theory of evolution. Creationism has no place in a science class though and most people recognize the Bible was never intended to be a science book. Now the theory of intelligent design is NOT the same thing although the left in particular likes to pretend these are the same thing -and some creationists like to grab that title to try and gussy up their creationism religious stuff. There are a LOT of scientists who believe the theory of intelligent design is the most scientifically sound answer to explain very specific phenomena in the natural world. But ONLY those specific phenomena. Scientists in nearly every single field of science have proposed the theory as the most scientifically sound answer to very specific phenomena within their field of science and why. Ministers and preachers offer up creationism -but the theory of intelligent design was proposed and supported by scientists themselves
as a result of their work only. The fact it HAPPENS to very superficially be consistent with some religious beliefs is COMPLETELY irrelevant. To demand it be rejected because it ISN'T outright contradicting some religious beliefs is JUST as STUPID as demanding we abandon scientific theories because it does contradict religious beliefs. Both are flat earth mentalities and neither are legitimate grounds for adopting or abandoning a scientific theory. Unlike creationism which is NOT scientific theory WHATSOEVER, the theory of intelligent design demands MORE scientific investigation, not less -and the minute a different explanation is found for any of the very specific phenomena for which it was proposed, it makes it less likely to be correct for any of the others as well. There is a way to DISPROVE the theory of intelligent design -while there is actually no way to prove the theory of evolution -and creationism isn't a theory at all but an issue of faith only. No legitimate theory FEARS a challenge and those who proposed the theory of intelligent design welcome challenges because THAT is what will increase our scientific progress. NEVER by demanding we shut down all challenges to whatever theory the left is trying to exploit for political gain.)
When a scientists comes up with a theory the left believes can be politically exploited for THEIR political gain -they grab it and immediately start politicizing it. It becomes a POLITICAL issue that becomes totally divorced from sound scientific practices and just outright manipulated in order to try and maximize its political exploitation. Those who glom onto a scientific theory do it ONLY because they believe it can be exploited for their own political gain -and once politically invested in it, can tolerate NO dissent. If they are in positions of power, they start demanding all challenges to it be silenced and those who would challenge it be PUNISHED. They start demanding everyone treat it as "fact" even though it never is. In spite of the very real fact that 99.8% of all scientific theories end up in the TRASH! It is the nature of science and how scientific discovery is made -a theory is proposed to try and explain a specific phenomenon and then scientists try to prove it correct -by trying to prove it is WRONG and does not explain that phenomenon after all. Only when the theory holds up to all challenges including those that change variables to see if it still holds up, is a theory EVER accepted as scientific fact. So the purpose of the left demanding all challenges to their pet theory be stopped and those who challenge it punished -is a demand to abandon sound scientific practices. There is only ONE reason to do that -it is because of their belief it is vulnerable to challenge and likely to end up proven wrong. Legitimate theories WELCOME the challenge -because that is how science moves FORWARD. Demanding it be accepted without putting it through established and sound scientific challenge is POLITICS only and when that happens, it means that theory has been corrupted and manipulated.
Politics and science are a LETHAL mix responsible for the MISERY, starvation, deaths and mass murder of MILLIONS. Just to toss out a few -the Holocaust was based on the scientific theory of eugenics.
The Soviets based their entire agricultural practices on a particular scientific theory called Lysenkoism -a disastrous theory about how to increase crop yields but only resulted in massive crop failures, increased poverty and resulted in several regions that suffered near starvation. Year after year after year, with those who became politically invested in the theory refusing to abandon it in spite of the obvious failures that proved it was a crock of shit. Scientific dissent from this crock of shit theory were officially OUTLAWED and opponents were often imprisoned or even killed and all were purged from the Communist party. Lysenko himself was instrumental in bringing about the imprisonment and death of hundreds of scientists. For the "crime" of DISAGREEING with his bullshit THEORY. Oh gee, does any of this sound familiar? THAT is what "science" looks like under the control of the far left. The Holocaust is what "science" looks like under the control of the far left. (And yes, Nazism was LEFTWING extremism, not rightwing.)
The left MUST be challenged as soon as they demand we all bow down at the altar of science anytime they find a new theory they believe can be exploited for their own political gain -and global warming was just one more theory they did this to as well. And they WILL continue doing it. For whatever reason, the rest of the world seems to forget the valuable lesson of what really happens by allowing the left to try and exploit science for political gain. Politicizing science invariably results in increasing human misery.
Sadly, although several scientific theories have been politicized by the left over the decades -in the end not ONE ended up being true. NOT ONE.
NOT ONE!
