Sharpest disagreement ▶ 24:40 China crushing the US in robotics and drones

The robot combat founder bluntly dismisses American competitiveness, stating China holds ninety percent of humanoids and that the US military is forced to rely on Chinese DJI drones.

 Hardest push from Greg ▶ 9:11 Challenging eight-figure defense contract claims

Greg stops and directly questions Mo on whether closing eight figures in DoD contracts within a single year on a 3D-printed drone is realistically possible.

 Biggest teaching moment ▶ 17:24 Organ-by-organ biological age diagnostics and AI modeling

The longevity diagnostics co-founder educates Greg on why measuring 460 biological markers is required before intervention, contrasting scientific modeling with misleading Instagram supplement fads.

 Greg holds their own ▶ 11:34 Greg articulates product vision and founder empowerment at Bolt dinner

Greg takes the room to articulate his core professional domain: bridging user feedback into software creation and helping founders manifest ideas into reality.
