That there are people who have to target multiple operating systems, and don't have 100+ people working on their team, right?
I mean...it doesn't take a genius to figure out that there's a benefit to being able to write code once and deploy to ALL users/customers without having to dedicate entire teams of developers with expertise in various platforms.
I'm an Android developer with 10+ years of experience. I take pride in my native apps that I code for the company I work for. They are far superior to any web app or "multiplatform framework solution".
But if I had to create my own personal app, there's no way in hell I'd spend years learning everything it would take to create a native iOS, Windows, Linux, MacOS version.
I'd be an absolute idiot if I didn't just choose a solution, like a web app, or framework that was able to output for more systems, etc.
