Interesting that the article emphasizes making development easier. I've dealt with a lot of low/no-code tools and my experience is that it only really seems to make common use cases easier. Seemingly this would allow developers to focus more on the difficult problems of programming, which inherently isn't easier, but probably makes the job more interesting. Setting up CMS's or building basic CRUD functionality can get old pretty quickly.
I don't see the appeal, by the time you learn to make simple things with these proprietary tools you could learn making simple things in Flutter, React Native and similar frameworks, which you can keep using for complicated things as well.
