I wonder how to reconcile the apparently exciting stuff going on in quantum computing with a conversation I had with a Harvard quantum computing PhD last year (I know very little about the field myself, so I unfortunately can't comment much on specifics here—I just know the guy was legit because of other people I knew who worked with him): he said he'd chosen the wrong field 'cause it has basically played out that quantum computing is intrinsically more limited and less exciting than what people had hoped for, and that a lot of big companies were starting to realize they'd wasted tons of money on it. (This was admittedly all being stated in an exaggerated and joking style, but he did seem serious about the basic idea.) Has there been something in the last year that's changed things? Or maybe his opinion was just an outlier? Edit: that could've been up to two years ago, thinking about it.
