Get all your questions about quantum computing answered by someone who's been doing research in the field (and explaining it to the public) for 25 years! Some say quantum computing will soon completely replace classical computing and will revolutionize machine learning, finance, medicine, and countless other areas. Others say quantum computing is a scam and impossible even in theory. Both are almost certainly wrong. The truth is much more subtle and interesting, but, being subtle and interesting, it takes more than a few sentences to explain.
