Heard the same thing from React Native - now some of the biggest (Slack, Zoom, Skype, Discord), most performant (Figma) apps are built on both.
Only way I'd have a take like yours is if I was a native dev, and my job security relied on companies hiring 3 people to lead 3 teams for 3 codebases (Web, Android, iOS native) - rather than 1 team and 1 codebase for all 3. I'd dishonestly dismiss the notion of cross-platform programming only out of self-preservation, and not any semblance of pragmatism.
