Absolutely! This is unlikely to directly, or even in the next 20 years, result in anything practical. But it has a very similar feel to Stothers' and then Virginia Williams' earlier improvement on matrix multiply, where his thesis and her first paper were followed by a dozen others finding ways to build on it after 20 years of seeing no progress on the problem at all. None of them have resulted in anything practical but who cares, really? Understanding the problem better is good and maybe some time in the next hundred years it'll result in an improvement in practice also. Or not. :)
