✅

VLA models are actually LVA-dominant due to language param weight — Solid (75/100)

👌

VLAs excel at nouns/knowledge but weak on physics/verbs — Opinion (50/100)

Fair roast of VLA limits — physics sim needed next ⚙️

Golden era? More like expensive pain fest 💀😂

UMI paper spawned unicorn startups Generalist and Sunday — Solid (85/100)

Hyperbole on 'greatest' but startups check out 👌

VO solves mazes via forward simulation in pixel space — OK (65/100)

Pixel space claim is half-right, often token tricks instead ⚠️

Nvidia's Dex-OOI exoskeleton enables fast direct data collection — OK (65/100)

Concept real, exact 'Dex-OOI' name fuzzy ⚠️

Teleop limited to 24 hours/robot/day, realistically ~3 hours — Solid (80/100)

Math don't lie — humans need sleep 😂👌

V3 skips geometry when 'not looking' in maze demo — Just Vibes (50/100)

Physics slop hack — genius cheat code 😂💀

Dex-OOI data trains fully autonomous robot policy, breaks 24-hour limit — Personal Story (70/100)

Nvidia demo — believes it, can't fully verify yet 😤

DreamZero: policy model dreams seconds ahead to act — Dubious (45/100)

DreamZero sounds Nvidia-fresh but no web hits yet 🤔🚩
