Challenges and Timeline
While world models offer exciting possibilities, LeCun cautions that significant challenges remain:
- Computational Intensity: World models require processing vastly more data than current LLMs, necessitating advanced computing infrastructure.
- Complex Problems: Many difficult technical hurdles must be overcome to realize functional world models.
- Extended Timeline: LeCun estimates it could take "years to decades" to achieve human-level AI through this approach, with a possible timeline of 5-10 years.
