More generally, I would say that Etherium itself is mostly nonsense. I will admit I don't understand very well what the purpose of the "blobs" are that are being discussed in the article, but from my perspective the entire idea of blockchain technology is not useful. I have yet to be convinced that there is any real problem being solved by it, but there are a lot of problems that are created, which then need to be resolved with ever more esoteric and unproven solutions, like what is described in this article.
