cherry picking examples does not mean the web MUST be slow, maybe the web apps were programmed badly... I can write even worse native apps than these web apps and it will not prove anything
did you ever try compile c++ code to webassembly and check out the performance "degradation"?
it still can be true that for this special task, a native app is the better choice and people would buy it from the App Store even if 30% more expensive
I mean nobody will and wants to take away the choice of using native tech. The degradation is on sooo many levels is not a necessity or consequense.
Web apps are not replacements, they are a choice, an addition. I really do not understan these kinds of comments that frame web apps as a compulsory security nightmare or replacing superior native with inferior web...
Safari stays, native stays, you and every developer can choose.
It may move better developers towards the web stack but then faster and better web apps follow. They will make use of web capabilities and technologies (like better js, multi core, web assemly, optimizations etc).
Chill! No self respecting company will publish inferior web apps if native is so much better in their special use case!
