My interactions with it were done to get a higher level of polish on some business related spreadsheets I was working on. I can manage certain tasks, but I don't use those skills often enough to warrant scaling my knowledge and practice to that level. A buddy recommended using one to give me the necessary formulas, so I tried it out.
Not one suggestion from the bot worked, and as it apologized and offered other non solutions I noticed recurrences of previous answers and a degradation of the quality substantial enough for a relative novice like myself to spot the issues before implementation. Perhaps it will advance past this point, but I'm unsure that the people in charge of them are really the folks needed to actually hit that target.
