A large tanker has blocked the Suez Canal. We discuss what it means for an already constrained shipping flow. Plus, we speak with the CEO of a company developing vaccine passports about the ethics of proving you’ve been vaccinated. And we talk about the three A’s of tech: Apple, Alphabet, and Amazon.
