I think this tends to overestimate the amount of time folks who
aren't developers want to spend developing. Most spreadsheets, even of the complex variety, exist as steps in a chain of human decisions -- they basically replace notepaper and calculators. (Spreadsheets that act as inputs to software chains are usually created by developers.)
Having previously been involved in architecting and building enterprise low-code/no-code solutions, and then working as a strategy consultant thereafter (including partnering with other major low-code/no-code vendors), I can say that what the business wants to do is sketch out the rough plan of how a process works (with a couple of exception states) and have someone else go through not only the implementation, but the hard work of dealing with all the error states, data cleansing and ETL, deployment, and monitoring, while they get on with the hard work of actually doing their jobs. There just isn't an appetite for people to do two jobs at once.
What the article seems to miss is that companies are currently being much more aggressive in nearshoring work -- there's a huge boom in Mexico and LATAM development that's pushing up salaries there (as has happened in Eastern and Central European states). One thing that's distinct from the offshore boom is that, if you weren't a major consulting org, your offshore folks probably weren't colleagues, whereas with nearshore you're much more likely to see them integrated into the organization (again, due to TZ and the ability to fly someone in at the last minute for meetings). It'll be interesting to see what this does to the Mexican/LATAM economies -- Costa Rica, for example, with only $5mm people, punches way above its weight in software services exports.
