To me, he talks more about boreout/brownout than burnout. The first one (I almost did it this year) is about having a job that is boring, like really boring for you (mine was tech support only with absolutely no control over anything, plus some disrespect for my company and client (big bank) starting to appear). Brownout is more on the lost of meaning which he talked more about.

Both may seems "better" than burnout, but being bored enough to have suicidal ideation back is not a great deal (in my case) and according to my therapist : the cause are different, but the result is "always the same" : one day, you can't get out of bed and cry...
