For web devs, it's easy to get excited about being able to deploy to iOS and Android. I find Expo exciting too.
However, where I see this being challenging long-term, is for purely native features (push notifications, Google/Apple Pay/Wallet, widgets, etc).
The ideal would be to have knowledge of both OS's, JS/TS and keeping up to date with the developments of React Native. This would be extremely difficult to find and maintain.
For this reason I believe iOS and Android devs are still needed and by the looks of it every web dev can by default be a mobile dev with React Native.
