I run a content agency and get this question a few times a week. Let me answer step by step, because just saying "yes" or "no" would be misleading.
First, let's understand what changed. The cost of generating text has dropped to almost zero. This means the value of the generated text has also dropped. Abundance doesn't equal value.
The conclusion here is: the kind of content AI easily produces is no longer a competitive advantage. If everyone can produce it, it can't be what sets you apart.
So is it useless? No, it helps, but in different areas. We've seen real benefits in these three uses:
Drafting. It beats blank page syndrome and builds structure. Then a human writes on top of it.
Editing existing text. Shortening long sentences, generating headline alternatives, catching inconsistencies.
Speeding up research — but verification is a must. We don't use any information without confirming it from the source.
Where it clearly doesn't work is experience-based content. If AI is making up sentences like "Here's what we experienced while doing this job," that text is a lie and readers can tell.
