Concrete where 'Potato starch replaces human blood', was this written by an AI?

Further into the article it mentions that earlier formulations used blood and urine. Other projects have used urine, so it's not shocking.

The bullet point does make it confusing, as it mentions the substitution before we even know it was used in the first place. There's some weird word order issues here and there (for example, "and you have a potentially revolutionary new material" where I believe it should have been "and you potentially have a..."), but I wouldn't think it's AI.
