I can think of none.
I can think of a lot. Zoom, for example. People on this board (and presumably you?) believe it will seize the space previously occupied by Facetime, Google Hangouts, perhaps WebEx. Granted it hasn’t done that yet, but the folks on this board seem to be thorough. So if they think it is a possibility, then it probably is. I would think investors are actually counting on it.
When was the last time you saw a Walkman? Or a Discman? It was the greatest thing ever, until it wasn’t. Almost overnight it was replaced with MP3 players. For a while iPods were most of Apple’s business rather than their Macs. That didn’t sink Sony, of course, since they are not a one-product company. But it illustrates how a product can be obsolete overnight, and if you are a one-product company that is a danger. Oh, and MP3 players have mostly been replaced by smartphones.
Blockbuster was destroyed by Netflix (primarily) in DVD rentals. Netflix then evolved to enable streaming so they didn’t get destroyed by other streaming services.
I could come up with other examples.
It’s a reality of tech. Something can come along and replace a product overnight. In fact, you can almost count on it. The disrupter can become the disruptee. Continued innovation is required or a tech company dies. That innovation fuels the growth that is the focus of this board (from what I can tell; I’m still new here but that seems to be the emphasis in Saul’s investing philosophy).
