I got reminded of it during watching Vivy (the new arc shows a lot of promise) but the topic of robot waifus reminded me of the anime Plastic Memories. The show's plot is in a not so distant futures where humanity developed androids.... and they have a life expectancy of the average iphone and needs to be rebooted at the factory at the end of that lifespan since they will otherwise develop a memory leak that will turn them crazy and dangerous. The hero has started working at a company who deals with retrieving the androids before they hurt anyone, which is pretty depressing when you have cases of people taking the androids as lovers or surrogate children/parents.
I haven't watched since it aired, but I like the show's twist on having the humans outlive the androids rather than the usual opposite that happens in media (and it's probably the more likely take on what will happen once we'll have somewhat organic looking androids) and I remember liking the cast and the different plots through the series.
And you can't talk about the show without mentioning the jump in the first episode:
