I'm more responding to the idea that programming might become simple and automated, and we can't even predict technological changes a year or two out. You're right that Python could be relegated to a niche language in 20 years. That does happen.
What hasn't happened is a fundamental change to programming languages since the 1960s, despite the incredible increase in computing power, ubiquity of computers and much better tooling and environments for programming languages. There's no evidence that this is going to change anytime soon. All the popular new languages are similar to the popular older languages. If people don't want to program in JS, they transpile from Typescript. Even web assembly is a means to use a language like Rust on the web.
There's no simple, automated PL on the horizon that is going to replace JS, Java, Python, etc. There isn't one for spreadsheets, either, which is a technology from the 80s.
