Berkshire Hathaway Vice Chairman Charlie Munger took no prisoners in attacking bitcoin during the multinational conglomerate’s annual meeting Saturday.

And to the surprise of no one, the bitcoin community on Crypto Twitter responded in kind, showing little to no respect to the 97-year-old executive. Some responders treated Munger’s attack as a stereotypical elderly person’s lack of tech savvy or even a “Get off my lawn!” type of outburst.

Other comments from Crypto Twitter took issue with Munger’s view that the leading cryptocurrency is bad for civilization when Berkshire Hathaway is a major owner of Coca-Cola, maker of sugary drinks, and has owned tobacco stocks over the years. Still others found it ironic he criticized bitcoin’s use in crime when many of the financial giants in which Berkshire has invested have been fined by regulators.
