SaaS is going to be dead. Think about how none of your friends subscribe to Twitter but they’ll gladly buy $150 shirt from Acmé de la vie. Software is too saturated, to easy to replicate. Only the things that are actually hard to build will survive. Hardware and mass following are hard to build, and hard to beat.
“Far better is it to do mighty things, to win glorious triumphs, even though checkered by failure… than to rank with those poor spirits who neither enjoy much nor suffer much because they live in the gray twilight which knows neither victory nor defeat” - Theodore Roosevelt
