There’s been various methods for blocking sperm from travelling down the vas deferens that managed to get through studies and then just got dropped.

Edit: This is what Wikipedia has to say on that topic:
Despite this, pharmaceutical companies are reluctant to lose market share of a thriving global market for female contraceptives and condoms which bring billions of dollars of revenue each year. Initially, RISUG attracted some interest from pharmaceutical companies. However, considering that RISUG is an inexpensive, one-time procedure, manufacturers retracted.

That kind of procedure would wipe out most of the contraceptive industry. And of course that can’t be allowed.

















Tbh, the biggest issue with Linux right now is that the GUI path to doing things differs too much.
You can do quite a lot of things via GUI by now, and I think that’s really important because GUI is much more discoverable. As in, not knowing what I need to do, GUI is more easy to figure out.
But the issue is that GUI changes a lot between distros, DEs or even distro/DE versions.
So if my mom (who is quite on the tech illiterate side and running Linux for years now) asks me a question, I don’t know how exactly the GUI on her distro/DE version looks like. But I can tell her some command line command that works on almost all distros.
That’s also why most of the stuff you find online tells you to copy some command into CLI, because CLI differs less.
The problem with that is that CLI is of course also much less discoverable. Once you learn where to look (help option of the command, man pages, tldr pages) and how the concept of CLI works in general, you can figure out stuff yourself. Or you just google, that’s ok too.
Right now, Linux works ok for tech illiterate masses as long as they know one guy who knows Linux quite well and they can ask them. Apart from setting stuff up in the beginning (which does require someone with a bit of skill), the tech illiterate Linuxers ask much fewer questions than the tech illiterate Windows/Mac users. So once it’s running it’s ok.
