I don't think it'll become the normal way. If anything, the opposite is true, people making Electron apps to get to access the power of web development, instead of making native apps.

It's definitely not easy, it requires you to re-implement everything from scratch. It only makes sense in cases where performance is paramount. I could imagine applications being migrated to the web doing it though, like Photoshop an the like.

But I absolutely don't see normal web development migrating over, it's just way too much pain for little value. Development, debugging, testing, etc. Everything becomes much harder.
