I am moderately pessimistic about the state of research because I do hear things I don't like, but this is compensated by my belief that US academia has a ridiculous amount of institutional entropy, and I'm perfectly willing with temporary issues if this means at least some of the long term problems will be improved. So overall... cautiously optimistic? Long term at least. Is that cheering?
And since the grandparent also mentioned visas - here at least I have a pretty simple opinion. Congress should step up and reform immigration laws. They've avoided doing this for decades, and it's kinda useless to put the blame anywhere else. (for context I'm not american, and my country just had the visa waiver canceled this year by the current administration, so I'm actually on the other side of the fence).
