I don't know why this isn't the top comment. I feel that Hacker News readers, despite their demographic, are often surprisingly averse to new ideas that challenge current tropes.
There are a number who are afraid of equity crowdfunding for the reason that some consumers will get fleeced. While that is an admirable sentiment, if it was frankly more genuine there would be more effort put into curbing the thousands of "financial vehicles", payday loan companies and MLM's that scourge the poor. This isn't that. Yes, we need limits and constraints, but there's too much at stake to throw the baby out with the bath water.
I think that it needs to be paired with an elaborate vetting process that still is missing in crowd funding projects. Why can't we have organizations that provide Technical Due Diligence, etc.?
In other words, I completely agree with you. Currently VCs (and many Angels) are like major label record companies: they are more risk-averse than they realize, they operate in a strict handful of myopic categories, and they are unashamed of the old boys network aspect of it. It's all ripe for disruption, and while the effect of that might mean some consumers will be cheated, we can mitigate that portion. And the upside is huge. You are right, it would absolutely "cause technology to accelerate even more in the future." The future could be much brighter if we can figure this out.
