There is a contingent that I think Marcus is responding to that have been claiming that all we need to get to AGI or ASI is pure transformer scaling, and that we were very close with only maybe $10B or $100B more investment to get there. If the last couple of years of research have given us only incrementally better models to the point that even the best funded teams are moving to hybrid approaches then that's evidence that Marcus is correct.
This website by a former OpenAI employee was arguing that a combination of hardware scaling, algorithmic improvements, etc would all combine to yield AGI in the near future: https://situational-awareness.ai/
