Here is an in-depth summary of the YouTube video "How Is AI This Good?" by Dylan Curious:

AI is rapidly advancing and is already being used in a variety of ways.

The video starts with a few examples of how AI is being used today. For instance, AI is being used to create realistic talking avatars, generate music, and even crush robots with liquid nitrogen. AI is also being used to develop new drugs and materials, and to solve complex mathematical problems.
