Many in the AI field think the bigger-is-better approach is running out of road
As if anyone is good at predicting the future.  Please can we stop acting like expertise equates to fortune telling capabilities?!  Nobody has any clue what a 1000x sized GPT model could do, and anybody who makes strong claims is a charlatan.  In this age of paranoid AI risk cultists we need to cultivate humility and calm, a willingness to follow data rather than beliefs and predictions.
