An advantage of scientific Chinese is actually how simple it is. Scientific vocabulary in Chinese only uses easy characters. Once the volume and quality is there, the users will soon follow. for physical sciences and engineering, every scientific term has long had a Chinese counterpart. CS falls behind a little, admittedly.I agree with you, but we need to be patient. English has been the de facto language of science for more than a century, and for good reason. When Chinese scientists produce the majority of the world's scientific breakthroughs, and I believe that day is on the horizon, it won't be long before China replaces English as the de facto language of science.
An example is, if you watch Three Body (Tencent version), they never speak English at all, even when talking about stuff like nanomaterials, astrophysics, etc.
