1) Deep Learning - people do that all the time
2) The Reinvention of the Data Center - data centers already exist
3) Virtual Worlds - aka MMORPGs
4) Digital Wallets - aka credit cards
5) Bitcoin Fundamentals - scam
6) Bitcoin: Preparing For Institutions - scam
7) Electric Vehicles (EVs) - still cost too much
8) Automation - has a 100-year history
9) Autonomous Ride-Hailing - self driving cars aren't safe, and a liability to the driver
10) Delivery Drones - not allowed within several miles of an airport, necessitating conventional delivery

13) Long Read Sequencing - human genome was sequenced 20 years ago with no significant benefit
