Staples and basketball nets already do their job well… no point wasting time on products that don’t need imporvement… there are a lot that do need improvement…
i have seen basketball nets made out of metal chain for use in public spaces that do last longer. but they also rust / corrode and can break apart into a bunch of sharp lawsuit-inviting pieces. so it is interesting to note that there has been some de-evolution of certain products also. besides, it would take longer to cut down a net with a blowtorch after a college basketball game.
as far as products that have remained relatively unchanged:
Cars have more or less stayed the same for over a century, sure there’s the alternative fuel concepts but the bulk of mass production vehicles all follow the same configuration.
