The criticisms of what the Boring Company has built are completely valid. I suggest you actually read them and consider them rather than just blatantly disregarding them because they might be interpreted as criticism of Elon.

Scrolling down the thread brings up statements about all environmental reviews, all satellite launches, and says that starlink is going to destroy humanity by ruining the atmosphere.

You're right that it's easy to mistake any statement like mine as being a blanket defense of Elon and dismissing valid criticisms, but this discussion as a whole has gone far afield of cement accelerators and chemical burns.
