While you make a valid point about the difficulty of instituting the technology, it is in no way “vaporware” as you suggest. This is something that continues to be actively researched for use in humans, and has already been effectively used in primates. You can see just one example of this below, but there are others.

I am supremely confident that this is going to become a widely utilized technology in the near future as our understanding of chemical polymer synthesis continues to improve. While it may not be today or tomorrow, it is certainly the area to focus money for continued research and development.

I’m happy for you that you found a solution that works for you, but there are 8 billion other people on this earth. Many of them may want a reversible solution (and/or) suffer serious ill-effects from hormonal or mechanical female birth control (IUD). More options is always better, and with the rise of authoritarian bans on reproductive healthcare in the United States, this is all the more reason to focus positive attention on emerging technologies that have the opportunity to protect the reproductive health of women.
