From looking up more usage, as it isn’t a word I often hear, it seems by nature to be neutral, but context can direct it to be more positive or negative.
If I heard someone say it in conversation, it would put a lot of emphasis on the tone of the conversation to take the meaning. I’d imagine it being used more sarcastically, as it sounds like a fancy word for someone with shallow knowledge of a subject.
“John won’t shut up about that trendy new art exhibit.”
“Oh yeah, he’s a real dilettante all of a sudden!” 😒
John had never shown interest in art before, but now that he saw it and either liked it or pretended to like it to show off his “higher appreciation of culture” than his friends now he keeps talking about it even though he doesn’t know anything about art.
I wouldn’t say it’s impossible to use in a positive manner, but being dismissive feels more likely. If someone used it that way I’d feel I was potentially missing out on a joke at first.
I love brewery wash for my water bottle! Soap or bleach always seemed to give me a funny taste or order. It may have been in my head, but I didn’t like it and it led me to cleaning it less often.
Decided to hit it with StarSan one time it got icky and cleaned it right up with no taste or smell.
I try to run it through the dishwasher more often, but if I put something odd in the bottle or it sat out for a long time, now I StarSan it.
