Knowledge in itself is good. We don’t need everything to have a direct commercial application. In fact most discoveries by their nature do not have directly applicable commercial applications.
Because those who pay for the taxes frequently don't. So some justification needs to happen to spend other peoples money. A better way would be nice, though.
This is a popular argument but there are plenty of things that cost orders of magnitude more taxes that go towards projects that lots of people don’t agree with. Americas trillion dollar war machine for example.
Well put. But, of course many on here don't have time for the concerns of simpleton non-elites, and whether they should have a say about where their money goes; I've noticed lately I look for the greyed out comments first on HN.
