we've also got some reaction from dr. fauci on the reinvention of the wheel, as well.

i must express cautious optimism around the wheel-reinvention candidates, as they have yet to pass randomized testing in sufficiently large trials. we are not yet clear if this particular approach to rewheeling will effectively eliminate friction, or if there may be unknown sources of friction coming from hidden variables, or perhaps even multiple dimensions. it is also not clear if the friction is being eliminated because of the rewheeling or due to some other effect, like sympathetic magic. i would cautiously avoid using this device to reduce friction for now, and continue to drag objects that need to be moved in sleds, as the egyptians did centuries ago. 

there was a follow-up about potential hyperthermia due to exertion, and a query as to why our previous understanding of the wheel was not sufficient.

look, we just don't know yet. i'll be the first to support a proper wheel-reinvention candidate when it appears, but until then we need to keep dragging ourselves through the mud.
