Are there limits to what AI can do?

AI is far more capable of data and information retrieval than humans are. There is a nearly limitless amount of information that can be collected on the internet, but humans do not have the energy to collect so much because they can get tired. AI does not have that problem, and can perform unsupervised learning at a vastly accelerated rate. AI can even replicate 3-D models, creating an avatar through wire mesh. Humans will usually generate models through green screens, but AI can replicate humans through all the image processing and data it has collected. 

An example of this is the Tupac simulation at Coachella, which simulated his movements and voice through the AI data mining body and speech recognition. Creating a 3-D model of Tupac took a great deal of effort, but as technology advances and data becomes increasingly easier to acquire, replications of singers can be done in real time. Even now, AI can scan objects and make a painting out of it, so the limits of AI and AI concepts seem smaller as time goes on.
