I have been reading the same prediction my whole life so I'm sure this will be a boom at some point by pure chance. But I tend to think that those solutions already exists, and the typical tool coming to mind is WordPress. You literally don't need to know code, just install some plugins that give what you want and go ahead. Pay someone to maintain it (there are tons of companies already). It doesn't need to be WordPress, there are many other platforms. For low code Django comes to mind.

For the very typical use cases there are well suited SaaS tools e.g. Shopify for shops.

I do think that the very typical cases are well covered. Sure, there's room for improvement but not sure if a real boom is around the corner but as I said I heard this so many times (and also seen so many tries) that well, at some point something may actually happen I guess.
