This is a frankly ridiculous take and completely misunderstands what makes Electron attractive.
There are no "Electron-based Mac apps", because nobody is targeting the Mac specifically with those apps. What we do have is web-first apps that use Electron to provide a desktop experience (like Slack), and desktop-first apps that use Electron as a multi-platform runtime (like VS Code).
The first group tends to have webview-based "native" apps and running those on the Mac wouldn't realise any of the expected advantages of a native app. The latter group won't have any sort of native iOS app to begin with. At any rate, neither of those groups is likely to migrate to native apps because of this move.
Does this support all iOS apps? Like Instagram? If so, do we need a separate software to run them or is it directly downloadable from the Mac App Store?
you can run any iOS app on an M1 powered mac. that said, it opens in a window only, and emulating touch actions requires you dig out a cheat sheet hidden in menus
Slack's iOS app is written in Obj-C and Swift[1]. I think the author's suggestion was that the macOS desktop app built with Electron will become obsolete because the superior iOS version will be able to run on macOS.
I would wager that that vast majority of electron app users, have no idea they are using an electron app and wouldn’t care if they did. I’m inclined to believe that the animosity towards electron is largely held by a pretty small minority.
As a developer I use several electron apps daily on a MBP, I never give them a second thought.
The inelegance of high memory consumption is far less infuriating than the many product and UX sins committed by apps.
If you're idling most of the time (which well written GUI apps and seemingly few Electron apps do) then execution overhead affects battery drain very little.
