It was hard to see from the video, but I suspect the machine he was on increases resistance as pedal speed decreases to try and keep him at a constant output.
That's a pretty common device for elite fitness testing.
As a lark, I built a set of personal productivity apps that are delivered as standalone local webpages. Works surprisingly well on Android, haven't tested on iOS.
This is great work. Most voice AI optimizes for latency - you made the opposite bet (quality over speed, frontier models over lightweight ones) and that's probably the right call.
The audio pipeline alone is impressive: on-device VAD, parallel TTS chunking, retry-from-failure mid-pipeline. That's not a weekend project; that's production-grade thinking.
Here's the thing that excites me most, though - the *cognitive layer* is wide open. The experience harness is solid, but right now every session starts cold. Persistent user memory, context that makes your 50th conversation meaningfully smarter than your first, light orchestration that turns a single question into a structured multi-step inquiry - that's likely where this goes next, and it's a compelling frontier.
Voice access to frontier reasoning is massively underserved. You've built the right foundation for it.
What a collosal missed opportunity for Trump. His supreme court was about to save him from himself and his ruinous tariffs. He could have continued to insist that his tariffs were genius while letting someone else take responsibility for bad outcomes.
Economy does poorly? Blame the supreme court for striking down his beautiful tariffs.
Economy does well? Take credit for shepherding the economy past a hostile court.
Remember, in his narcissistic mind, Trump can never fail he can only be failed.
Instead he's now insisting he'll restart the tariffs under some even more flimsy interpretation of executive power.
That's a pretty common device for elite fitness testing.
