I draw a distinction that you don't here. Development is not about the expansion of knowledge, it's about producing things. Science is about the expansion of knowledge.
As a society, we very often conflate the two, but they're really very different things.
They're very intertwined. A paperclip factory produces things; they don't do tech development (shouldn't do much at least). Tech development is about pushing the edge. Science, obtaining more knowledge about the universe we have to work with, helps, but it's also about finding new applications for what we've already known.
Tech development doesn't necessitate the production of things, even intangible ones. Technology development in the form of new optimization techniques in existing software for e.g. rendering 3d models or searching data faster or whatever is not producing things, but it's still tech development.
Technology is the practical application of knowledge about the world. Science is the acquisition of such knowledge. There certainly can be an overlap in the Venn diagram here, but the distinction remains valid and important.
In any case, I was not saying that your perspective is incorrect. I was just saying that my worldview seems rather different from yours.
If there's none, why is expanding our knowledge of what we can do and how any different?
