Three years to take over so many parts of several industries seems overly optimistic. Optimistic to the point of it just being used as a boogeyman to keep wages low. "Why should we hire you when AI can do your job?" is a sentence I am sure employers would love to use more often in job interviews. Doesn't matter if it's true or not when the threat seems real.
I've been following the AI workflow to 3D from the beginnings and that's pretty much where we're still are. The bottlenecks are tight with no solution in sight yet. The AI model passes the torch to conventional algorithms quite early in the process so to speak. And even when this changes, it'll be a nice tool to have, but not so much the autonomous swiss army worker the businessworld keeps dreaming and warning us about.
So yeah, don't worry about us, journalist. It's coming for you first.
