I always enjoy going to Steve's talks. He covered the topic well and had everyone taking notes and asking questions. I now want to follow up on the topic and learn more.
Steve was easy to understand and his slides were clear.
I thought that the talk flowed well from talking about CLI strategies and best practices from UNIX to a basic overview of WP-CLI and Symfony Console.
It would have been nice to see or learn about Symfony or WP-CLI methods in the secure arguments section.
