And, honestly, can you blame them? Nerdy places such as HN have a fascination of fundamental science that is nearly religious in some aspects - not in a sense of dogmaticism, but in a sense that pursuit of abstract knowledge is seen as noble and desirable in and of itself, with any justifications distinctly secondary. But from the perspective of your average person on the street, today, scientists are those people who ask for a lot of money, and use it to build those giant things that run some incomprehensible experiments which occasionally translate to some equally incomprehensible headlines in the news. And that person can think of many ways in which said money could be used to make their lives better instead.
Now, you can reasonably argue that long term, benefits are there regardless, even if they are not obvious, and thus the people actually in charge of allocation resources should disregard such simplistic takes and focus on that long term. But, either way, one cannot be surprised at the discontent.
