I’m glad that you’re finding this useful. When I say it’s useless, I speak in my name only.
I’m not afraid to try it out, and I actually did, and, while I was impressed by the quality of the English it spits out, I was disappointed with the actual substance of the answers, which makes this completely unusable for me in my day to day life. I keep trying it every now and then, but it’s not a service I would pay for in its current state.
Thing is, I’m not the only one. This is the opinion of the majority of people I work with, senior or junior. I’m willing to give it some time to mature, but I’m unconvinced at the moment.
