PendingTerafab: AI5 small-batch 2026, volume 2027, a terawatt of compute/year
“We either build the Terafab, or we don't have the chips, and we need the chips, so we build the Terafab.”
“My guess is that AI roughly doubles US GDP growth next year from ~2% to ~4%. Maybe even more.”

The fine print
Deadline = end of calendar 2027 ("next year" from Sep 18 2026). Resolves on US real GDP growth rate for 2027 vs ~2% baseline — pass if roughly ~4% or higher. Distinct from #117 (double-digit growth), #254/#261 (economy size doubles), #196 (10x). Hedged as "my guess" / "maybe even more" but falsifiable annual growth figure.
