I was invited to speak at AI Show Biz in San Fran, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I was working while speaking at the event. It took me 20 hours to prepare for my 20 minutes speaking slot, and I had a mostly good time. I'm a woman who has been speaking for 7 years. This was a for profit event.
