Already-established top-of-the-market apps will not be dethroned overnight.

For them, it will be a slow death (e.g. similar to how Figma unseated Adobe in the digital design art space).

As for new app markets, you will surely see (compared to past generations) smaller organizations being able to achieve market dominance, often against much more endowed competitors. And this will be the new normal.
