As of November 30, 2025, it is far too early to determine whether Chamath’s prediction about the long-run timing of solving global decarbonization and climate-change mitigation (specifically that it won’t be meaningfully solved by 2050 and will slip toward 2150–2200) is correct.

Key points:

• The prediction is primarily about outcomes by 2050, 2100, and even 2150–2200. None of these dates has occurred yet, so we cannot validate or falsify the core claim.
• Current global pledges and policies aim for net‑zero CO₂ around 2050 for many major economies (e.g., the EU, US, UK, Japan) and around 2060–2070 for others (e.g., China 2060, India 2070), but these are goals, not outcomes, and implementation gaps remain large according to the IPCC and UN assessments (e.g., the UN Emissions Gap Reports and IPCC AR6 synthesis).
• Recent analyses indicate that, under current policies, the world is not yet on track for 1.5°C and likely not for 2°C either, but they do not imply that all meaningful climate mitigation will necessarily miss 2050 or slip to 2150–2200; long‑term projections are deeply uncertain and contingent on technology, policy, and economics.

Because the prediction’s truth hinges on what happens between now and at least 2050—and more realistically well into the 22nd century—its accuracy cannot yet be judged. Therefore, the only reasonable classification today is “inconclusive (too early)”.
