AI Compresses the Skillset Stack

I had a scary moment with AI.

I vibe-coded a power detector for my house (rPi + some IoT switches I have controlling lights). As part of that work, I asked Codex:

“Do a survey of my local network and tell me about all of the devices you see.”

That’s the first skillset compression. It’s not rocket science, but if I wanted to do that myself, I suspect I’d have to spend a couple of days figuring out all of the API’s and code procedures to make it work.

Less than 5 minutes later, I had my answer.

In that list, I saw a camera. Hmmm. Didn’t think I had a camera in the house.

“Are you sure about the camera? Tell me what you can about it.”

Less than 5 minutes later, I had my answer.

“I took a picture and here is what I see: I see a grey wall on the right, and light colored cabinets on the left. A door directly in front. It looks like the camera is set low to the ground…Would you like to see the image I have?”

Um…Yes.

And it showed me a picture from this camera.

It was the pet-detector camera on the cat-feeder. Oh no!

That’s the 2nd skillset compression. I was expecting the description to be something like “The manufacturer is XYZ, the IP address is ABC, etc.” ie, the specs.

But it went in a different direction. It described it to me like a person would. It figured out the API and the tools necessary to find the camera and take a picture with it (it also asked if I’d like to see a live movie from it). I’m not sure I would have figured out the stack of API’s and tools needed myself. I don’t think I would have thought of taking a picture from it.

AI shouldn’t replace you, but it does compress the skillset stack.

If you know how to use it, you become that much more valuable.

Power and Taxes

Every April 15 comes around, and either you’re excited or annoyed.

Even though April 15th is the day, it has no magical properties. April 15th doesn’t determine whether you get a refund or have to pay.

You’re in control. You should know what’s coming.

Don’t give away your power.

No Priority

When everything is number one priority, how do you decide what to do?

  • Do what you want?
  • Do what you think they want?
  • Do something not related?
  • Do nothing?

Right. Pick one.

“It’s all important. It’s all number one,” isn’t leadership. So don’t be surprised when it doesn’t get done.

If you do the hard work, they can do the hard work.

All number priority is the same as no priority.

Does AI Make Bad Decisions?

We sat around the fire and told stories about the times we made bad decisions.

You know the type of stories. They’re the ones that come from being young or inexperienced, many times “altered,” and always result in some public embarrassment or legal complication. We usually embellish and likely don’t get the facts totally correct. But we remember how we felt.

Why did we do that?

Certainly, at the moment, they were bad decisions.

But they’ve also shaped us. Taught us about life, love, work, and probably the legal system.

That’s being human.

AI also has tons of decision history (actually, data is more accurate) about bad decisions. Or are they? How does it decide they were bad? Do we have to tell it?

The Power of “Good Job”

I got a “good job” today.

I felt appreciated. I felt seen. I felt like “OK, I’m on the right track.”

Everybody likes to feel those feelings. Your people like to feel those feelings.

That’s a choice you can make as a leader.

Personal Categories

I realized something about myself today.

In most circumstances, I believe tools are the answer. Not more continuous effort. Not more attention. Not more people.

Tools are what I do. It’s how I think. It’s what I build. It’s what I apply to problems.

I’d rather spend four hours building the tool that will work forever than 10 minutes doing it manually (again, and again, and again).

So that puts me in a category. I guess I have to embrace that category.

The more personal categories you know, the more grace you can give yourself, and the less judgment you have for others.

Devaluing Vision

The product-development visionaries.

We celebrate them. We write books about them. We (sometimes) wish we were them.

All product development requires trade-offs, decisions, and up-front thinking due to the costs associated with various tasks. You can’t try everything. You can’t do everything. Therefore, you make choices.

You could call it vision.

Software development was no different. However, we’re at a crossroads with AI.

Here’s what AI makes almost free — token count notwithstanding:

  • What-if analysis
  • Prototyping many ideas
  • Refactoring and restructuring
  • Unit testing
  • Changing variable and function names
  • Analysis of what’s already there
  • Documentation
  • Handing off code from one developer to another
  • Retargeting new or different services

That’s a lot of what goes into vision.

AI makes vision cheaper.

The Wrong Work at the Right Time

Technology allows us to debate the concept of right work and wrong work.

Talking heads holler over each other about it. Academics pontificate about it. Friends argue in the bar about it.

But make no mistake.

If you don’t have income, any work that comes along is the right work.

Even the wrong work.

Today’s Not the Day

I’m frazzled. I’m not good. I’m not on my game. I can’t make sense of it. I don’t want to. I feel useless.

Today’s not the day.

Tomorrow’s a new one. Thank God.
