I don't mind putting a bit of cash towards projects where those involved really don't have the resources to pull it off otherwise, but does Neal Stephenson really not have enough cash to bootstrap this himself?
It offends and infuriates me that you don't see any value in the creation of new technology other than "give me interest". Your species of cynical profiteering is the reason we have freewheeling boom and bust cycles with no significant social benefit.
These people already have the resources and industry support to do what they want to do (the exquisitely produced videos are themselves a testament to their resources!), but for some reason, they're asking the man on the street to carry a share of the financial risk in exchange for no share of the returns.
As interesting as the idea is, if you contribute to this Kickstarter you're a chump.
The production alone on that video
