Why? Is this a higher research priority than other medical conditions such as cancer or HIV? Are there plausible reasons to think that epic scale funding would significantly accelerate results?
Of course it's not the #1 healthcare priority now but who says we should only solve problem #1 and leave all the others hanging?
I know a health worker that worked hard to save lives during the first phases of Covid and her life is now ruined due to this. I doubt she can be 'cured' but at least this may be prevented for others.
Further, many of those conditions share enough common traits that it's plausible that insights into one will generate insights into others.
