Today, Meta Platforms gave a first look at an in-development AI tool called Builder Bot. In essence, Builder Bot works like a voice assistant for quickly sketching out virtual worlds. The company hopes such assistants will help spur creativity—and, by extension, economic activity—in the metaverse. It’s a compelling idea, and one that could go a long way toward making Meta’s virtual worlds popular in the long run if the company can pull it off.

But that’s a big “if.” As a proof-of-concept it looks promising, but nothing about actually building and then responsibly deploying such a tool will come easy.
