I don't really agree with the last paragraph. BOINC was not designed to not be a coin mining service or to be an alternative to other mining as I read between the lines. BOINC existed well before coin mining.
It's the flexibility which BOINC offers which makes it hard to optimize. And it is this same flexibility that will make it hard to make it enter IOT devices. Except maybe the bigger ARM powered ones.
We agree that BOINC was not made to be a coin mining service.
Also that the lack of BOINC project uniformity is an issue to overcome in the future, but I think the benefits of BOINC's flexibility outweigh its drawbacks. Particularly because I think BOINC can be built as an ASIC resistant platform without losing too much of its flexibility.
I think we mostly agree but that paragraph just isn't very clear = )
