I think you're misconstruing the author's argument, at no point does the author imply that Claude knows best, or that Electron apps are better. Their closing argument is certainly not an endorsement for Electron or AI slop.

Don’t get me wrong: writing this brings me no joy. I don’t think web is a solution either. I just remember good times when native did a better-than-average job, and we were all better for using it, and it saddens me that these times have passed.

I just don’t think that kidding ourselves that the only problem with software is Electron and it all will be butterflies and unicorns once we rewrite Slack in SwiftUI is not productive. The real problem is a lack of care. And the slop; you can build it with any stack.

They also bought the Bun JS company, didn't they? Maybe they actually can improve the spp a bit by replacing Node with Bun.

Also, which native UIs do people like coding up? Most UI toolkits have JS bindings, don't they? So only HTML/CSS is the bad fit?
