This Valentine's Day, Elon Musk wants you to know that machines will take over the world and make you obsolete

Let's be clear here: What Musk is proposing may be far-fetched, but it's a response to a very real problem that's going to affect a lot of people in the near future. Jobs that involve predictable manual labor are in danger of becoming obsolete. McKinsey & Company estimates that about 78 percent of those types of jobs (along with 69 percent of data processing and 64 percent of data collecting) could become completely automated. Driving-related jobs are likely to become increasingly automated as self-driving technology improves, and given that those were the most common jobs in 29 states as of 2014, we should absolutely be focused on finding a solution. But Musk has also floated a much simpler--and more realistic--solution.
