The nuclear famine paper I analyzed earlier lied about this
I think it pays to have a higher bar for calling something a “lie”. The paper does explicitly state their assumption that stores last only one year. You provide good evidence that this is a bad assumption, and it’s possible that it was made in bad faith (i.e. the authors maybe knew it was a bad assumption), but I think calling it a lie based on current evidence causes more heat than light.
I don’t think you have any object-level disagreement with most people who say AI is “about to” shake things up. You just view “the tech is already such that this could theoretically be happening today” as sufficient justification to say things are being shaken up in the present tense, while others are using that same justification for the words “about to”, and are presumably waiting for real-world effects (significant shifts in commission art pricing, artists losing their jobs, any major project shifting their art budget to use this tech, etc.) before we say the shake up is actually happening.
