Cardano founder Charles Hoskinson and Ripple CTO Emeritus David Schwartz mocked OpenAI CEO Sam Altman after he argued that underused memory in home computers should be redirected to AI data centers. Higher memory costs could affect independent XRP Ledger and Cardano node operators, according to BeInCrypto. Hoskinson’s meme said he uses 64GB of RAM, matching the XRP Ledger’s recommendation for its server software; Cardano’s developer portal lists up to 24GB for a mainnet stake pool. SK Hynix has forecast a memory shortage until 2030 as AI demand outpaces production.
