| 0:00.0 | The following is the conversation with Scott Ernson, his second time in the podcast. |
| 0:04.8 | He is a professor at UT Austin, director of the Quantum Information Center, |
| 0:10.3 | and previously a professor at MIT. Last time we talked about quantum computing, |
| 0:16.4 | this time we talk about computation complexity, consciousness, and theories of everything. |
| 0:24.0 | I'm recording the central as you may be able to tell in a very strange room in the middle of the |
| 0:32.2 | night. I'm not really sure how I got here or how I'm going to get out, but |
| 0:38.9 | Hunter is Thompson saying I think applies to today in the last few days and actually |
| 0:45.7 | the last couple of weeks. Life should not be a journey to the grave with the intention of |
| 0:52.1 | arriving safely in a pretty and well-preserved body, but rather to skid in broadside and a cloud of |
| 0:58.3 | smoke thoroughly used up, totally worn out, and loudly proclaiming, wow, what a ride. |
| 1:08.6 | So I figured whatever I'm up to here, and yes, lots of wine is involved. I'm going to have to improvise |
| 1:16.0 | hence this recording. Okay, quick mention of each sponsor, followed by some thoughts related to |
| 1:21.6 | the episode. First sponsor is Simply Safe, a home security company I use to monitor and protect |
| 1:27.9 | my apartment. Though of course, I'm always prepared with a fallback plan as a man in this world |
| 1:36.0 | must always be. Second sponsor is 8th sleep, a mattress that cools itself, measures heart rate |
| 1:44.9 | variability, has an app, and has given me yet another reason to look forward to sleep, |
| 1:51.1 | including the all-important power nap. Third sponsor is ExpressVPN. The VPN I've used for many years |
| 1:59.2 | to protect my privacy on the internet. Finally, the fourth sponsor is BetterHelp. Online therapy, |
| 2:06.8 | when you want to face your demons with a licensed professional, not just by doing David Goggins |
| 2:12.6 | like physical challenges, like I seem to do on occasion. Please check out these sponsors in |
| 2:18.1 | the description to get a discount and to support the podcast. As a side note, let me say that this |
| 2:24.5 | is the second time I recorded a conversation outdoors. The first one was Stephen Wolfram, |
