@purrperl a million eyeballs is less practical than the tools we are developing today.
Finding 1,000,000 to care about ncmpc (as just one example of an open source project) would be really difficult. It shouldn't be, but we do a poor job of teaching computer literacy to people at the moment.
That alone might spark more interest in free and open code, especially given what the alternatives are.
And many bugs are non-obvious, which is why projects like the Linux kernel, which sees a lot of eyes, still has critical vulnerabilities.
We can either learn to use the tools or hope they poof and disappear, and I don't put great odds on that happening, as the current-day tools are already being leveraged to do some serious work (most of it bad, because it is not in the hands of the masses.)
The way the tools are used has almost always been the problem, with every tool we have so-far developed. Moderation is key.
