1. Just a rhetorical weapon. Leave it at the door so we can discuss your specific domain, sociopath to sociopath. (1 2 3 4 5)

2. A response to the media saturation of Techcrunch startups that threatens to suck all the talent out of the economy. (1 !2 !3 4 5 6 7 8 9)
Rebuts 6 and 9.
Tangent: knowledge loss. (1 2 3 4 5 6)

3. A call to aim higher. A willingness to call out crap ideas, attempts at value capture without even a fig leaf of value creation. (1 2 3 4 5 6 7 8 9)
Rebuts 10. Contested by 5.

3a. A reminder for vigilance; it's easy to slide past hard problems because they're terrifying. (1)

4. A cry for help, and a warning of social unrest. My need is greater, but nobody's thinking about it. You're covering my 1% use-case, the top of my hierarchy of needs, but not my 80% use-case, the bottom of my hierarchy. Ignore me at your peril. The bet. (1 2 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 ?24)

5. Oblivious to the realities of how entrepreneurship happens in the world. Often good works don't pay like value capture does. To ignore this is to tilt at windmills. (1 2 3 5 6 7)
Contested by 3.

6. Guaranteed to be narrower in your head than in reality. Stop telling others what to work on. Just work on whatever you consider to be most important, and let everyone else do the same. (1 2 3 4 5 6 7 8 9 10 11 12 13 !14 15)

Red-herring: market vs regulation analogies. Technology is a black-swan business. Regulation is useless in black swan domains. (1 2 3 4 5 6 7)
(Potentially resuscitated by this comment that I haven't fully processed: 8)

7. A misguided attempt at making technological evolution legible. (1 2 3)

8. A perpetual complaint. Somebody always has to be at the bottom. There'll always be real problems, and you'll always be able to claim we can do more. (1 2 3)

9. Incomplete. There's lots of useful work going on. It just doesn't get covered on TechCrunch. So get off your ass and go read something else. (Ok, don't bother getting off your ass.) (1 2)
Rebutted by 2.

10. Superficial. Major companies are indeed solving real problems. It's just happening in the backend where it isn't visible to the world. A lot of it is open-source and could have unanticipated benefits. (1 2 3 4 5 6 7 8 9)
Rebutted by 3 and 11.

11. A rationalization. If you're hoping that whatever you build will unintentionally help mankind then your brain has been captured by your circumstances. (!1)
Rebuts 10.

12. Fuzzy. The only thing that's 'real' is scale. Everything else is a wall constraining your thinking (Senthil: super blindness). (!1)
How to define scale? Needs more discussion.

13. An unproductive argument. (1 2 3 4)
Rebutted by all other arguments, in descending order.

! - Particularly insightful comment.
? - I'm more likely than usual to be misinterpreting/miscategorizing this.
