Disclaimer: we still have pragmatic reason to follow the evidence suggested by our best scientific theories. I'm just poking fun at scientists in the spirit of Hume. There's no guarantee that the future will resemble the past, and even our best scientific theories are amenable to future evidence.
We aren't even disagreeing now but you would rather argue than grasp the point. Point being, the presuppositions of science are not themselves within the purview of science. All our best theories start with axioms.
You continue to talk about the usefulness of science, which I conceded before you ever typed your first comment. At this stage, I have to assume that you're being willfully obtuse.
You said you were poking fun, I poked back. I appreciate the conversation, I enjoy thinking about these things.
