Artificial intelligence sometimes gets a hard time, especially in Hollywood with many films showing robots taking over the world. But other experts say machines and technology could also be a huge force for good, creating and improving jobs, safety, healthcare and education.
Meet Will, believe it or not Will isn't human. But he is the first digital teacher and is only real in your computer.
Will is going to teach primary school children in New Zealand. He can interact with students on a computer, tablet, or mobile phone, and has been teaching kids about the environment and renewable energy.
He can respond to the answers given by children and can react to their body language. During Will's trial, the children said, "If we smile at him, he smiles back to us."
Perhaps taking inspiration from New Zealand, some university classes in London are to be given a futuristic spin by showing lecturers as holograms.
Imperial College London has been testing the technology and say that expert guests from all over the world will be able to deliver classes without having to travel.
A similar effect has been used to animate images of Michael Jackson, Elvis Presley and other famous celebrities.
