Maybe the onus is on the skeptics to conclusively prove that web3 is BS? Since none can effectively prove so, then maybe it is not BS?
The skeptics are always inventing new reasons why it will fail, and yet it's still here and bigger than ever, day after day, making the skeptics seems crazy at this point, pointlessly arguing for lack of use for something that is clearly useful, judging by the sheer amount of capital and development resources used, if nothing else.
