One of the sources on energy consumption per transaction has been written by an analyst who has admitted in interviews to knowingly misrepresent the data by structuring it in a certain way. I’m not gonna dig up references now. “kWh per txn” is bunk and DR is either aware of that and deceived you knowingly or is unfit to give lectures at this point, but does it anyway.

Another is a 2018 paper on “mining very bad mmkay” from an author who lunched his own proof of stake coin and now has undeclared conflicts of interest measured in billions. Presented as an impartial credible source.

The entire “lecture” just appears to be an ideology piece for those that enjoy Malthusian doom porn.

Which is fine, I guess, if you go to a Jesuit academy instead of Stanford.
