The internet has a sustainability problem. Many of its critical services depend on the dedication of unpaid volunteers, because they can't be monetized and thus don't have any revenue stream for the maintainers to live on. I'm talking about services like DNS, time synchronization, crypto libraries—software without which the net and the browser you're using couldn't function.
These volunteer maintainers are the Load-Bearing Internet People (LBIP). Underfunding them is a problem, because underfunded critical services tend to have gaps and holes that could have been fixed if there were more full-time attention on them. As our civilization becomes increasingly dependent on this software infrastructure, that attention shortfall could lead to disastrous outages.
I've been worrying about this problem since 2012, when I watched a hacker I know wreck his health while working on a critical infrastructure problem nobody else understood at the time. Billions of dollars in e-commerce hung on getting the particular software problem he had spotted solved, but because it masqueraded as network undercapacity, he had a lot of trouble getting even technically-savvy people to understand where the problem was. He solved it, but unable to afford medical insurance and literally living in a tent, he eventually went blind in one eye and is now prone to depressive spells.
More recently, I damaged my ankle and discovered that although there is such a thing as minor surgery on the medical level, there is no such thing as "minor surgery" on the financial level. I was looking—still am looking—at a serious prospect of either having my life savings wiped out or having to leave all 52 of the open-source projects I'm responsible for in the lurch as I scrambled for a full-time job. Projects at risk include the likes of GIFLIB, GPSD and NTPsec.
That refocused my mind on the LBIP problem. There aren't many Load-Bearing Internet People—probably on the close order of 1,000 worldwide—but they're a systemic vulnerability made inevitable by the existence of common software and internet services that can't be metered. And, burning them out is a serious problem. Even under the most cold-blooded assessment, civilization needs the mean service life of an LBIP to be long enough to train and acculturate a replacement.
(If that made you wonder—yes, in fact, I am training an apprentice. Different problem for a different article.)
Alas, traditional centralized funding models have failed the LBIPs. There are a few reasons for this:
