There are too many factors that'll decide whether it'll be success or not. I believe timings and luck are often overlooked.

iPhone certainly not the first touch screen display, Microsoft did have one, I believe. However Apple's timing was perfect, there was increasing adaptation of wifi connectivity and 3g, making it able to browse anywhere. Of course smoother interface and beautiful design also contribute big.

AmongUs was lucky they got advertisement from streamer, at perfect timing that was (is) pandemic and lockdowns.

Tesla can be considered crazy because they try to emerge with unknown product, with unknown market and unknown possibility of success. If we look at the past, Apple's iPhone was crazy too, because it was new product, with unknown market.
