Verizon's CEO says SpaceX needs 4–6 years and up to $500B to build out a Starlink mobile network. Elon Musk: "Will take 2 or 3 years". People doubted him when Tesla was on the brink of bankruptcy, and it became a trillion-dollar company. They doubted reusable rockets until SpaceX landed them. Taking on terrestrial telcos? Betting against him usually doesn't age well.
