Even with an Apple ][ I doubt they could become true heirlooms. Most of them already broke down, and there's no way the survivors will survive 50 years or longer without having all internals refurbished.
Although that's not nearly as bad as this one. SSD, fan, LCD, RAM, battery are all wear parts that won't survive a decade on average, and the rest is only marginally better.
