No human can translate as fast as ChatGPT, they can’t even type 30 words that fast. If you want to say that a human can make an improved translation sure, but they can still do that most easily with an ai first draft. They can get extremely close just by pre-prompting with the context required. And then they can do even better by taking their improved draft and offering it to chatGPT for suggested improvements. Frankly it is quite bizarre to claim you can do better. (btw do your translations get proof read - or are end users totally dependent on you doing an excellent job too?)
