The quote clearly implies support for the statement: it says a superintelligent AI could "leave no survivors" and "end humanity for good," which is an existential threat. Although it refers specifically to superintelligent AI and is conditional, that still establishes the author's view that AI can pose such a threat to humanity.

Confirmed. Vitalik Buterin’s official website lists the 2023-11-27 post “My techno-optimism,” and that post contains the exact sentence “But a superintelligent AI, if it decides to turn against us, may well leave no survivors, and end humanity for good.” This supports both verbatim wording and attribution to Buterin.
