Bicycles have pretty much always been very durable machines. I have no idea what the longevity of e-shifting components is going to be, but mechanical stuff has been lasting for many, many decades.
i must have very bad luck with mechanical derailleurs. only perfect briefly until the cable stretches or something gets wiggled or who knows what, then the clicking starts and then after a while there's a shift in the middle which doesn't shift quickly, or doesn't shift at all, just goes click click click until the next shift and then it shifts twice. maybe 11 and 12 speed mechanical was just a bad idea to begin with.
no doubt these things can be fussed with until they're perfect, but by comparison my (only) di2 bike is completely trouble free, perfect shifts every time. snick snick. it seems like a genuine improvement with no downside other than cost.
