There can be multiple reasons for the same outcome in a complex system. Prevalence of social awkwardness at certain developmental stages due to variances in individual immutable developmental schedules should remain stable over short time frames. Unless you think the researchers/teachers are incompetent enough to have not accounted for the baseline levels of social awkwardness, then the fact that some people are awkward because genetics or whatever is an irrelevant point to make.
Are there any open source tools/projects worth contributing to that don't need specialized infrastructure, proprietary data, or a PhD in the field to understand?
Almost certainly yes. For example, lots of things don't have tests and really should. But I'm not too sure about priorities, or about which projects would welcome that work.
How is it that nobody seems to know that every major editor has either vim mode or a vim plugin. I love vim, but I almost never use it directly. I usually use JetBrains IDE with vim plugin. Best of both worlds.
I've used a great many editors/IDEs and within a day of installing any vim mode or plugin I find multiple inconsistencies or errors that make my life worse.
Exception being spacemacs/evil, which is why that's the only thing I prefer using over vim
