There is a cost-quality tradeoff companies are willing to make for AI model training using synthetic data. It shows up fairly often with AI research labs and their papers. There are also upcoming tools that remove the noise that would trip up some advanced models during annotation. Knowing this, I don't think the "human-labeled data is better" argument will last that long.
I stumbled upon Theo's Instagram page a while ago and I was stunned at how cool his inventions are. I'd really underrated how well one could bridge engineering and art.
