Haven't worked on Workday and the like yet to understand how "Cloudy" they trully are.
That's going to be a long time being automated.
For instance, if (for example) you model insurance data in the EU, you cannot use gender as a factor in pricing (even though it's effective).
In general, the modelling/ML pipeline is the easy bit, the hard part is the data cleaning and figuring out how to translate a business problem into one that can be solved by data.
tl;dr as many people have said about Comp Sci over the years, learn the fundamentals (statistics and experimental design) and you'll be in a much better position.
I would be very careful before dismissing AWS’ no code/low code project. Mulesoft, Microsoft Flow, and Zapier have a combined revenue of hundreds of millions of dollars a year in serving a market for establishing business logic workflow without code. I am only surprised it took AWS so long to move into the space considering the cross marketing opportunity to existing customers and their compliance capabilities.
What exactly do you mean by this:
'“senior application developers” who munge JSON in C#'
Why did you choose to JSON and C# in particular here?
I really hate the current pattern of getting some interesting topic and nice data about and burring it into 20 pages of story telling journalism.
