It takes time for developers to get the device and begin writing software for it. As time marches on, those things that we all find value in get bought by Apple or Google and become the default apps for things. If someone then decides to try something crazy, cool. If not, someone else later will make a competing device that tries. If it wins, cool. If it doesn’t, someone will make it way later still (like Apple recreated what General Magic was working on way later).
