Is it sophisticated? Maybe. Is it the alignment problem? Exhibits qualities of it, yes. Is it surprising? No.
The event strikes me as reminiscent of one's first go at programming, without familiarity of computer code: Tell the computer to do something obvious. Why the heck did it do that instead? Over time, one learns how the computer thinks. Apply this to any novel system. Or perhaps aptly any system with capabilities that are yet to be well understood by its user.
The article is trying to spin mystic out of simple bullcrap. Maybe that's just my viewing through turd-tinted lenses after the last few years of reading this drivel on repeat. More plausibly it is true that we've forgotten our own baby steps.
I don't think it's surprising, per say, but that's a consequence of the fact that I don't believe there is some sort of magic threshold at which a system becomes agential.
Like I don't necessarily disagree with any of your framing. The thrust of the alignment problem, as I see it, is that there is an intrinsic problem of aligning the goals of two distinct systems that poses catastrophic risks precisely when one of the systems is significantly more capable (in some sense or other, maybe not in a general/absolute sense) than the other.
