I get what you're saying and agree in spirit, but I think it is zooming out a little too far to say that technological development is just another natural process. Yes, it is in a way, but things like computation are truly different beasts. No, humans are not special in terms of our importance, language, meaning, or even intelligence, but my thoughts are that technology is a separate process from natural processes. It is distinct from evolutionary processes.
If you have some interesting reading, I'd love to know it. I haven't necessarily considered the question of technological processes being an extension of natural processes.
I think it's okay to accept something is true in an "ultimate sense", but not in a practical sense. e.g. that all technology is a natural process since the causal chain that led to it happened or rather was allowed by physics. To wit, plastics really are natural because humans evolved to be able to make plastics. If you argue against plastics being natural, then you might argue that anything "made" by an individual organism is artificial, which is clearly absurd.
No super interested in finding a resolution here, since I don't think the common meanings are problematic.
By the way, I think you're in a tiny minority if you believe there is no distinction between things that evolve and things that are designed.
