Google unveils Genie 4: interactive worlds with sound, about two minutes long
Genie 4 generates interactive worlds with more realism and built-in audio, starting with trusted testers.
Google showed a program that builds a world you can play in from a short description, with sound too. It lasts only about two minutes and only a few people can use it now.
