Computers have the option of a replacement hardware where humans do not. Perhaps to tweak the analogy and suggest the computer is specialist hardware running software designed for it that runs a stupidly expensive CNC made by a company that no longer exists. That changes the equation such that spending more than the computer hardware is worth is now worthwhile. And 2. If you have chronic fatigue it’s nothing like fatigue a healthy person would experience - it’s next level. There were some thoughts to change the name to mild paralysis because sometimes you can be so fatigued that you literally cannot move. There are objective ways to measure it. Post Exertional Malaise has a number of tests, two day max exertion test for one. There are also immuno assays which are pretty definitive. You can take plasma from someone with ME/CFS introduce healthy white blood cells, expose it to a salt water stress test and measure how quick the cells run out of energy and the results are definitive here too. Hard to fake that. As for the subjectivity, when looking at post viral fatigue there seems to be 3 categories of people; 1 people who appear to be incapable of getting post viral fatigue, they'd die before reaching some threshold which suggests that there is a genetic aspect to susceptibility. 2 people who grew up with a progressive ME/CFS who are highly susceptive to post viral fatigue but consider the fatigue within their normal experience. 3 people who don't have ME/CFS but are at least partially susceptible, specially with Covid, and anecdotal accounts of their experience tends to have a common thread of never had experienced that level of fatigue before in their entire lives.
