Sirji, I can understand where you're coming from about the junior sde part, won't same hold true for associate pm or whatever?
It's like saying tech advancements would remove first officers, only captains will remain to fly commercial airplanes, there's always nuances to it.
The label may or not exist but the technical human would remain, a pm who understands code spitted from magical black box is also a sde, (infact that could be real quality check for unqualified PMs, some of these can't even use Google sheets properly, let alone AI).
After all, existing N number of drag and drop website builders haven't taken away business from "freelance web developers".
