@blacklight I don't think the knowledge is lost. It's just not worth using it for deskop computer applications. A gigabyte of RAM is the same price as an engineer working for a few minutes. Even if you multiply it by the number of people running the app, it will not compensate the costs. So, no one will be paid to save that gigaby.te of RAM.

Also, there is some survivor bias here. What about all the space probes that failed because of stupid mistakes?
