Who told you that? You can write entire C libraries and call them from Electron just fine. Browser is a native application after all. All this "native applications" debate boils down to the UI implementation strategy. Maintaining three separate UI stacks (WinUI, SwiftUI, GTK/Qt) is dramatically more expensive and slower to iterate on than a single web-based UI with shared logic
We already have three major OSes, all doing things differently. The browsers, on the other hand, use the same language, same rendering model, same layout system, and same accessibility layer everywhere, which is a massive abstraction win.
You don't casually give up massive abstraction wins just to say "it's native". If "just build it natively" were actually easier, faster, or cheaper at scale, everyone would do just that.
Value prop of product quality aside, isn't the AI claim that it helps you be more productive? I would expect that OpenAI would run multiple frontends and that they'd use Codex to do it.
Ie are they using their own AI (I would assume it's semi-vibe-coded) to just get out a new product or using AI to create a new product using the productivity gains to let them produce higher quality?
Our IDE does this: common code / logic, then a native macOS layer and a WPF layer. Yes, it takes a little more work (less than you'd think!) but we think it is the right way to do it.
And what I hope is that AI will let people do the same -- lower the cost and effort to do things like this. If Electron was used because it was a cheap way to get cross-platform apps out, AI should now be the same layer, the same intermediate 'get stuff done' layer, but done better. And I don't think this prevents doing things faster because AI can work in parallel. Instead of one agent to update the frontend, you have two to update both frontends, you know?
We're building an AI agent, btw. Initially targeting Delphi, which is a third party's product we try to support and provide modern solutions for. We'll be adding support for our own toolchains too.
What I fear is that people will apply AI at the wrong level. That they'll produce the same things, but faster: not the same things, but better (and faster.)
