"Not in the slightest" is an overreach, the paper the second level down from that link doesn't really support the conclusion in the blog post - the paper is much more nuanced.
Are they going to fib to you sometimes? Yes of course, but that doesn't mean there's no value in behavioural metaqueries.
Like most new tech, the discussion tends to polarise into "Best thing evah!" and "Utter shite!" The truth is somewhere in between.
You're retreating from your position. You started at "major step" and "extremely important", and you've arrived at "there's not no value".
> Like most new tech
It's nothing like "most new tech". Most new tech tends to be adopted early by young people and experienced techies. In this case it is mostly the opposite: The teens absolutely hate it, probably because the shitty AI content does not inspire the young mind, and the experienced techies see it for what it is. I've never seen such "new tech" which was cheered on by the proverbial average "boomers" (i.e. old people doing "office jobs", not the literal age bracket) and despised by the young folks and experienced experts of all ages.
