Verbatim quote
I I would maybe massage Elon's stated timelines for delivering arbitrary payload masses to the moon in light of the fact that we even though we've made we as a civilization have made major progress in delivering Starship progress, orbital refueling hasn't been demonstrated and that's a necessary condition for getting to the moon.
Resolution evidence
Alex is correct that Starship Mars/Moon timelines slip; orbital refueling demonstration not yet completed as of April 2026. Musk's mass driver 10y claim aggressive.

Calibration plot (stated vs observed)
Evidence about this node from Alex Wissner-Gross is multiplied by κ in /api/intake. Lower κ = less weight; floors at 0.10 (effectively silenced) and caps at 1.00 (full weight).
Reference class: mars_uncrewed_landing_window
Successful uncrewed payload delivery to Mars surface within named transfer window
Tetlock-style outside view: at TRF=1 (just predicted), outside view dominates (w_in=0.3). At TRF=0 (deadline), inside view dominates (w_in=1.0). The blend regularizes overconfident inside views toward the historical base rate.
