A great resource yes, but what value does the output have if anyone can create the same? People aren't thinking this through in terms of longevity. If skills are easy to get, they become valueless. This means that even if the output is okay, what will give it value is the skill applied after.
For example, if one of the people using it now and I were to put in the same keywords (starting from the same base text) and then spent time editing it before posting - what will the difference in result be?
Which will have more value? Life experience and skill still matter in that context. Nearly everyone can kick a soccer ball - not many can kick it like Ronaldo or Messi.
You're right, but I'm not talking about having it write anything, I'm talking about using it as a research assistant to get you other sources you can use and maybe summarizing them for you as a way of telling you if they are useful to then read yourself.
Even if one were to use its writing (after editing), it should only be one source of many to avoid the exact problem you mention, sounding the same as everyone else. I remember in high school English Class, my teacher required us to have at least ten sources for every paper we wrote so that we wouldn't all sound the same.
