I would be really scared to have something like this in me. If there could be guarantees that it would work as its supposed to then it will be alright but if they are already talking about the possibility of a hacker attacking it then that is scary right there.
If this means one would never forget the pill as they never want babies then get proper surgery. I do not think cutting ones self open for this is wise. Use the pill and condoms, or other methods but long term side affects are always scare to me and best avoided.
I don't want to sound crude but why would anyone want this in them unless they are a prostitute? You're not talking like its a disposable but something that goes on for almost 2 decades! There are bound to be complications. Better to get snipped if you don't want children.
