No. Electron "developers" may say that. The vast majority of us, do not in fact say that.
I've yet to actually see any argument directly from someone involved, in favour of electron apps besides "it was just or a web app" or "it's quicker/cheaper this way".
If I throw a bucket of house paint over your Honda, that's also quicker. That doesn't mean the result is really what anyone would consider 'acceptable'.
But, I think my pedantry does not dissuade from your actual point; making a modern MacOS program requires that you have a macOS machine- It also precludes learning a language that typically only runs on that platform (I know swift is cross platform but none of the windowing libraries that you'll use are).
Making tailored software per platform is tedious, making the same program multiple ways so that it can be native is just time consuming if nothing else.
Electron is an ugly way of fixing that; but it does the job of fixing it- Qt is an ideal solution in theory but it's obviously too much of a burden on developers to adopt.
I only hope it's from the second half of 2013: https://www.macrumors.com/2018/06/04/macos-mojave-supported-...
Eh? No it doesn't.

The cutoff would be either 2008 or 2009 depending on line.
16 GB DDR4 cost $200 now. This is not low-end, this is reaching premium levels. I got an entire mid-range smartphone for $165 last month.
