I've been using a fullstack low code development tool for several years now, and when it comes to developing CRUD apps or data reporting apps (with charts, interactive, drill down reports, etc. etc.), it's astonishing how quickly you can stand-up a secure, fully responsive web-app, complete with authentication, authorization schemes, report subscriptions, etc., without writing any code at all.
And, when you bump up against the limits of the declarative/low-code aspect of the framework, you can toggle over to java script, your own CSS, SQL, etc., so it's not like you paint yourself into a corner.
So, I agree, if Amazon creates something like this, and it is as good as some of the existing low-code tools out there, it's going to have a big impact over the long term.
