He criticized the shift of investor focus towards refinery and dollar store stocks, highlighting that AI's transformative impact is yet to be fully realized. Cramer believes AI is still in its early stages, likening it to 'batting practice' and suggesting it could replace physically demanding jobs and aid underfunded businesses.
