I would joke something akin to that's why china is winning but that would be too much bad karma for me to handle

technology wont count as the prayers were not written out by someone with reencarnatory mojo at a monestery, and then the prayer wheel sold to help both the new owner with carma and the monk and temple survive with money,also the physical action of spinning the wheel while the one holding is praying would count as intentional, a remote powered machine may likely be a stretch, or most likely with buddists,"bit prayers", ha! would have value inversly proportional to there speed of execution, lest the ancient megga temple prayer wheels loose there "value"
