That still doesn't address the root of the problem, which is that TUIs and Electron apps are write-once, run-anywhere, while native GUI dev is insanely fragmented.
I mean, I guess that's more or less just a summary of the blog post, but it's true. And it will remain true until the fragmentation ends, and the fragmentation won't end until Microsoft gets its act together and ships their version of SwiftUI so that some sort of abstraction layer over SwiftUI/GTK/MsftUI can be created. And since Microsoft will almost certainly never get its act together, the problem will remain.
In other words, not a blip. The UIs of the present and future will all be Electron apps and TUIs.
What does it matter how fragmented the platforms are? I feel like this isn't sinking in with people. I was chatting with a friend last night about a SwiftUI app that I'd built and he'd pitched in on. He then reimplemented --- didn't port it, reimplemented it, for WinUI, that night, with just a couple prompts.
I am, in a proverbial sense, buying puts on Electron.
