AI Hurtles Ahead

When I was preparing to write my December memo about artificial intelligence, Is It a Bubble?, I gained a great deal from speaking with some interesting techies in their thirties and forties. It’s stimulating to explore fresh territory and an absolute requirement for staying current as an investor. It’s one of the most enjoyable parts of my job.

I recently returned to those people to follow up on the December memo. As part of that process, someone suggested I ask Claude, Anthropic’s AI model, to create a tutorial explaining artificial intelligence and the changes that have taken place in the last three months. I did so, and it gave me a great deal to work with. This resulting memo is intended as an addendum to December’s. Much of it will recap Claude’s 10,000-word essay, to which I’ll add a few observations of my own. In the process, I’ll highlight some terms that were new to me and might be new to you. I could have saved myself a lot of time by asking Claude to write this memo, but I decided not to, because I consider putting words on paper a big part of the fun. I will, however, quote liberally from Claude’s work product. That’ll be the source of all quotations that aren’t otherwise identified.

Before I start in, I want to try to communicate the level of awe with which I viewed Claude’s output. It read like a personal note from a friend or colleague. It made reference to things I’ve talked about in past memos, like the sea change in interest rates and the pendulum of investor psychology, and it used them in metaphors related to AI. It argued logically, anticipated points I might make in response, injected humor, and bolstered its credibility by candidly acknowledging AI’s limitations, just as I might do. I’ve asked AI questions before and gotten answers back, but I’ve never received a personalized explanation like I did in this case.

Understanding AI

Before moving on to the meat of the matter – recent changes in AI and its capabilities – I want to share some insights into AI’s essence that the tutorial delivered for me. Importantly, the tutorial taught me not to think of an AI model as a search engine that retrieves data and regurgitates it. Rather, it’s a computer system that’s capable of synthesizing data and reasoning from it.

There are two phases in the life of an AI model. In the first, it is “trained” by reading a vast amount of text. The training phase must not be thought of as loading the model with information, which I had done until now; it goes far beyond that. It consists of teaching the model how to think. By absorbing text, the model learns:
