It will actually change a lot. There’s a famous saying in physics: “Science makes progress one funeral at a time.”

Specifically, according to Max Planck: “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”

Obviously, politics is much more biased than physics, so deaths will have an even more progressive impact. Boomers (and Gen X) are ideologically bankrupt with views radically divergent from those of younger generations and scientists generally. The reasons are obvious: culture, wealth, lead poisoning, etc.
