ACTUALLY, NO. There will always be the human error of carelessness, so long as there are humans doing things.
Here's a pretty famous example.
I'M NOT IMPRESSED.
I CERTAINLY WANT TO THINK SO, and have even mentioned a possibility or two. For example, consider the topology of a modern vasectomy: It basically diverts sperm output from the testicles into the main body cavity, instead of letting sperm reach the prostate. Well, imagine installing a Y-shaped valve in the vas deferens. When the valve is set one way, it diverts sperm into the main body cavity --and when the valve is set the other way, it lets sperm reach the prostate. It should work as very effective reversible sterilization for men (after setting the valve to "divert" a man needs to wait a few days to clear out sperm already in the prostate, but setting the valve to "connect" will probably let fertility be restored in a few hours). The only valves I've ever heard about before are simple on/off valves, and (according to what I recall) they tended to cause the vas to burst from pressure of sperm trying to get through. Not good!
ULTIMATELY, artificial wombs will be an alternative to pregnancy. minnie616 has pointed out multiple times the difficulty of moving an unborn human from a live womb to an artificial womb --better all around if it simply starts in the artificial womb.
Here's some recent news which could give lots of women a reason to get their tubes tied. They can get parts of their ovaries saved for later egg-production, in-vitro fertilizations, and wanted pregnancies (or, eventually, implantation in artificial wombs).
