Kind of, but frankly I think that’s a self-defeating hair to split.
What ultimately matters in the end is simply “is more carbon going into the atmosphere, or less?” It doesn’t matter where the carbon is coming from, all that matters is that less carbon ends up in the atmosphere.
If I have a plastic object and I send it for recycling or whatever, some of that carbon ends up in the atmosphere. Possibly all of it if it ends up being incinerated, since a lot of plastic “recycling” is not really recycling as you’d expect. If I put it in the landfill, on the other hand, the carbon is locked away effectively indefinitely.
It doesn’t matter where that plastic object came from, I’m just faced with a choice of what to do with it.
That’s not how synthetic data generation generally works. It uses AI to process data sources, generating well-formed training data based on existing data that’s not so useful directly. Not to generate it entirely from its own imagination.
The comments assuming otherwise are ironic because it’s misinformation that people keep telling each other.
