You are looking at this with hindsight bias and are assuming that for some reason the future will remain the same as the past. There are no fundamental reasons why ios and android development occur with two different ui frameworks in two different languages.
With low interest rates companies will not be able to justify paying 3x to maintain 3 different apps when they could theoretically just pay 1x for one app that works everywhere
The key word here is “theoretically”. These cross platform solutions are great in theory - who wouldn’t want to share code across all platforms? It’s a great sell, especially to the folks holding the purse.
The reality though is it doesn’t work well. The tooling, performance, debugging, library stability and observability are all substantially worse. Your team might save a ton of time spinning up a React Native app, but lose it all right back once you keep hitting gnarly Android performance issues.
In the future, once we have a proper cross platform development kit officially supported by Android and Apple, code sharing will be great. But today it doesn’t exist. And that’s why none of (the good) apps you use are written in a cross platform way.
Good metrics for proposal to VCs .. to steel the cake from native platform overlord. Lets eat the apple and google cake to boost our return margins. Bam! VCs alliance for new scene graph renderer for the web on any device.
