Enter a prompt into ChatGPT, and it becomes your very own virtual assistant. Enter a prompt into ChatGPT, and it becomes your very own virtual assistant. Why do your homework when a chatbot can do it for you? A new artificial intelligence tool called ChatGPT has thrilled the Internet with its superhuman abilities to solve math problems, churn out college essays and write research papers. After the developer OpenAI released the text-based system to the public last month, some educators have been sounding the alarm about the potential that such AI systems have to transform academia, for better and worse. "AI has basically ruined homework," said Ethan Mollick, a professor at the University of Pennsylvania's Wharton School of Business, on Twitter.

Avatars, chatbots and virtual assistants are getting smarter by the day, and the AI that powers them is helping customers get more of the right content at the right time. But humans will remain as important as ever. Nigel Piper looks at how (wo)man and machine can work successfully in tandem.

Is Nokia the latest tech company to join the growing niche of companies investing in AI voice assistants? By the looks of things, it could be so. The Finnish company has even filed for a trademark that would name its own virtual assistant as "Viki." Just this Sunday, GSMinfo revealed that Nokia has applied for a trademark in the European Union for its very own AI assistant. The EU reportedly received the application a few days ago and per the document, Nokia described its new technology as a "software for the creation and monitoring of mobile and web assistants working with digital knowledge and combining all data sources into a single chat and voice-based interface."

Google, playing catch-up with Amazon's surprise hit Echo speaker, unveiled a rival device called Home that promises even more dazzling artificial intelligence. The Home, slated for release later this year, will be powered by the impressively chatty Google Assistant, a voice-activated rival to Amazon's Alexa and Apple's Siri that Google execs said can better understand human speech and complex queries. Google Chief Executive Sundar Pichai -- who took the reins of the search giant last year after founders Larry Page and Sergey Brin created its holding company, Alphabet -- showed off the assistant's abilities at Google's annual I/O developer conference Wednesday in Mountain View, Calif. In addition to showing it ordering movie tickets, arranging travel and answering trivia questions, Pichai demonstrated how the Assistant can answer queries about photographs. It can even group them into surprising categories, like those that show "hugs."
