Prediction AI timelines and forecasting

Andreessen said he was pretty confident that within roughly two years of June 2023, AI systems' limited persistent memory across sessions would be a solved problem.

Mixed Partly true and partly false in roughly equal measure.

The second judge would not resolve this claim; the verdict shown is the first judge's.

What would count as true or false

The claim is that by about June 2025 the limited persistent memory of AI systems across sessions would be a 'solved problem'. The test is judged as of 30 June 2025. TRUE: by that date, leading consumer AI assistants, such as ChatGPT, Claude or Gemini, offered generally available persistent memory. They had to retain and use information from earlier sessions automatically, and contemporary expert or industry commentary had to treat cross-session memory as essentially solved rather than a major open limitation. MOSTLY TRUE: such memory was broadly deployed and working by the deadline, with only minor caveats, such as availability limited to certain tiers or regions. MOSTLY FALSE: memory features existed but were limited, in beta, or narrow in capacity, and were still widely described as a significant unsolved limitation. Being solved only after June 2025 is also mostly false at most. FALSE: by mid-2025 there was no meaningful cross-session memory in leading AI products, or the problem was widely seen as largely unsolved.

    “The Gemini app can now reference your past chats to learn your preferences, delivering more personalized responses the more you use it.”

Reasoning

By the deadline, ChatGPT did have cross-session memory that used past chat history, but it was tiered. Full chat-history memory was limited to Plus and Pro users (E2), and only a limited version was rolling out to free users in June 2025 (E1). Google's announcement that the Gemini app 'can now reference your past chats' is dated August 2025, after the deadline (E4). No evidence covers Claude, and none shows expert commentary treating cross-session memory as solved; commentary that did exist criticised how the feature worked (E3). The evidence shows partial deployment, not a clearly solved problem, and it also does not show memory still widely described as a major unsolved limitation.
