It’s Thanksgiving here in Palo Alto, and I should thank all the writers and producers whose work I read each week for the stimulation and provocation they provide. In case you do not all realize it, you are appreciated.

I always try to call out the creators of the content I curate at the top of That Was The Week, and I will continue to do so. Many appear every week.

Let us start with Brian Chesky, of AirBnB fame, this week. His X post is apt and to the point.

I called this week’s newsletter A Tale of Two Weeks. Friends kindly noted that it has only been one week. It felt like two, and to Brian Chesky’s point, we learned a lot.

EA and e /acc are now part of everyday conversation in tech circles. And we are starting to understand that ideology (or philosophy) plays a significant role in strategy. People are forced to take sides.

Last week, the EA (effective altruism) camp looked in the ascendancy. But this week, over 700 OpenAI employees sided with Sam Altman and Greg Brockman, resulting in their return to lead the company. The e/acc camp won. And that leads many advocates of effective altruism to question its relevance to startups.

There are also some new acronyms or labels to learn. Marc Andreessen is reposting @beffjezos on X, mentioning Decels.
