Totally agree. Drive belts are becoming a thing more and more, which I would deem to be a disruption. Far less maintainence is needed, no oil involved, no chain links, they last way longer than chains etc.
But these obviously only work on single speeds or enclosed-gear hubs. For derailleur-style gearing a change away from chains with the properties you described would actually really be a good thing, although I do not see it coming. With regards to power loss, chains get better and better, though.
