swim lanes

2025-12 – December Newsletter

In companies with significant AI adoption, there’s a new issue involving “swim lanes”. In the past, a marketing person typically wouldn’t implement a prototype, and a programmer wouldn’t propose a marketing plan. But with recent AI models, both of those examples now happen. A non-programmer can do “vibe coding” using sites like Loveable to quickly turn an idea into a prototype. And a programmer can use AI to craft a pretty solid marketing plan. Which means you see toes getting stepped on. It’s going to be interesting watching how companies handle this. They can try to enforce swim lanes, but in doing so they hamper innovation.

learn modes

All of the big 3 AI services now support “learn modes”. Each one is a bit different, but they all are trying to provide a better experience using AI to learn about a new topic. In my use case, I was trying to understand what a friend’s antibody therapeutics company does – I know it’s for treating cancer, but not much more. So the question I asked ChatGPT was: Explain “full-length human IgG bispecific and and trispecific antibodies that bind to multiple targets” to someone who has a technical background and a college degree, but knows very little about cancer treatments. ChatGPT walked me through an increasingly deep explanation, and then started asking questions to see whether I was retaining the information.

Asking AI for diverse ideas gets you more diverse ideas. OK, sounds lame, but it’s actually pretty cool. This is the research paper, but the idea is to add something to your prompt that asks the AI to generate results with more variance. This helps avoid you being trapped in the “bland, generic, same-old” response trap that exists in all of the current AIs. For example, instead of saying “Tell me five jokes about nonprofits”, which returns fairly uninspiring results. Try this prompt: “Tell me a joke about nonprofits. Generate 5 responses to that query, each within a separate tag. Randomly sample the responses from the full distribution”.

You can now edit images directly inside ChatGPT. For example, you can upload an image and then ask it to make a specific change. Here’s a snippet from a flyer I uploaded. I prompted ChatGPT with “Modify this image, by changing the times from 1:30pm – 3:30pm to 9:30am – 11:30am”. So….not exactly what I wanted 🙂 In theory you could ask it to tweak the background, adjust colors, or remove text. I haven’t tried this, but you should be able to generate variations of an image, like turning a photo into a hand-drawn sketch style.

This is Your Brain on ChatGPT. The MIT Media Center published a paper on the cognitive impact of using AI when writing. Ethan Mollick had a good response to this, which I (mostly) agree with. I think the key point he brings up is that all new technologies have both positive and negative impacts, with two examples being calculators (the fear that we won’t be able to do math in our heads) and cell phones (we won’t remember phone numbers) – both of which weren’t exactly earth-shattering, though note I said cell phones, not smart phones, which is a whole different story.

2025-06 – June Newsletter

There’s an interesting challenge with providing an appropriate persona for the AI to use when answering a question. If you make the persona too general (e.g. “You are an expert lawyer”) then the answer to your question won’t be as good as if you make it more specific to your question (e.g. “You are an expert in California labor law”). But if you’re using AI to help you explore solutions to a problem, then making it too specific (by assuming what the solution should be) will mean you don’t get the full benefit from AI’s ability to brainstorm and think outside of YOUR box. E.g. “You are an expert in litigating labor disputes in California” presumes that the solution to a workplace problem involves a lawsuit.
