I don't think meant that as snark at all tbh. They're saying they like that we're using synthetic processes to make biodegradable, useful, and known-safe materials in a more efficient way, as compared to making the usual synthetic cotton-alternative materials that have a lot of downsides by comparison (lack of biodegradability, poor breathability, microplastic pollution, etc). I think you two actually agree probably? Lots of synthetic things are bad or flawed, and it's nice to see this synthetic thing that is probably good.

Synthetic fibres are cool stuff, no doubt, but they also contribute to our whole microplastics problem, which isn't that cool, to be honest.
