Hmmm, perhaps econo-political diatribes could be avoided...
... for awhile in this case.
This appears to be decent research, and inasmuch as cardiovascular disease is a killer particularly in Western societies, I would be inclined to give the researchers some credit for possibly valuable findings. It's not like they're claiming a Holy Grail, just positing a new diagnostic tool.
"Lily Peng, a doctor and lead researcher on the project said that it was early and they were working with small data sets. In future large data sets could provide deeper insight. One of the problems with this study was that it could look at eye images at 45 degree views and this could miss out vital zones in the retina. Researchers are trying to correct this problem with new versions. Although more research is necessary, the team still calls this a major step towards 'non-invasive' diagnosis and predictor of cardiovascular health." Linky
I would prefer, for once, not to connect every damned thing with the sins of Google, or of Microsoft, or of Apple, or of Canonical, or whatever. Just let the research stand (or fall) on its merits. But that's just me.
