Mind Readings: Stop Reinventing The Wheel With AI

Summary

In today's episode, I explain why you should avoid using generative AI to solve deterministic problems that already have efficient, purpose-built solutions. Here's what this means for you. You will save computational resources and achieve more consistent results by matching the right tool to the right task. You'll also learn these concepts: the distinction between probabilistic and deterministic tools, how unnecessary AI implementation wastes compute power, and how to identify when software vendors add AI features without adding actual value.

Key Takeaways

  • You'll learn how to distinguish between probabilistic language models and deterministic tools for more reliable results
  • You'll discover why using AI for tasks like code formatting or spell checking wastes precious computational energy
  • You'll see why you must demand more meaningful AI integration from software vendors instead of accepting unnecessary features
  • You'll recognize the value of using existing specialized libraries rather than forcing AI to reinvent them

In today's episode of Mind Readings, let's talk about not reinventing the wheel. One of the most important things that you can do, particularly if you're doing things like vibe coding, uh, or I guess you know, AI pair programming, whatever fancy term you want to do for it these days, is to not reinvent the wheel and to not let AI reinvent the wheel. Let's say you're working on a project, maybe you're making a browser-based video game or something, and you say, I want it to be interactive, I want it to have all these fun features, etc. And then you set it off and it goes and it builds a game engine. Well, do you really need to do that?

The answer is no. If you're building a browser-based game, there are lots and lots of existing game engines that exist. Uh, there's one called Phaser that is very good, free to use, uh, and highly effective. You do not need to have AI rebuild a game engine from scratch. That's a waste of compute power, it's a waste of time.

Likewise, when you're doing uh program and you're trying to get it to fix certain types of errors. There are, as an example, in Python, so so so many tools that you can use that are deterministic tools designed and purpose-built already to solve errors, to fix problems, to clean up code and stuff. Do not let AI do those things. Especially because generative AI models are probabilistic, which means that given the same prompt, they will not do the same thing each time. So you may say, hey, clean up my code, fix this code, and it will say, Great, I'm gonna do that.

And unless you have very strict templates for it to follow, you will have random different coding styles throughout your application that are very difficult to manage because you it doesn't necessarily follow the same style unless you explicitly declare it. If on the other hand, you use something like um uh rough or black um or my pie or autopep 8 in Python, those are deterministic tools, purpose-built code-clean tools that will do that for you. That's so that you don't have to do that. There are tools, for example, if you're working with data frames uh in Python to do data manipulation. There are tools like Pandera that will clean up uh pandas data frame, so you don't have to have AI try and do those things because it's not good at them.

AI is not good at those particular tasks because it is a language model, language has variation in it. When the more deterministic a task is, the worse a fit it is for AI to do it. Because if you say this is the exact standard that you must meet 100% of the time, it will struggle. They can do it, but they're not as good at it as a deterministic tool that's purpose-built for that. In even in writing, um there are you you could have generative AI try to do spell check, right?

That's a waste of compute. It is a waste of compute when the existing spell checking tools are perfectly capable of doing spell check and fixing identifying and fixing items, and you don't need to spend that much compute power. If you have concerns about sustainability of generative AI in terms of how much resources it uses, how much electricity, how much fresh water it uses, don't use it for deterministic tasks where existing tools are have solved that problem. I see this a ton in marketing when we look at things like SEO tools. There are so so many people who are using generative AI to reinvent the wheel.

Like here, let's let's do an analysis of the keyword density of this page. A, you're doing a quantitative task and AI can't count. It's a bad idea right off the start. Uh, and B, that problem was solved. That problem was solved 25 years ago.

We had tools like uh term frequency inverse document frequency measurement, which is a statistical technique that can identify keywords on a page. Very low compute costs. You can run it on a phone. It's a simple algorithm. And that even is you might have the question, is that even worth doing any age of gender of AI?

Because it may not be. But at the very least, you should not be using AI to do that task of uh of doing keyword density on page. It's a waste of compute power, and it's gonna suck at it compared to a cool that was already built. Now, here's the here's the challenge. Now, this is a challenge for all of us who work in the marketing field, and all of us work uh with software companies.

Every software company feels like they have to say their product contains AI so that um they stay competitive so we're keeping up with the Joneses. We, as the buyers of these tools, have to be discerning buyers and say, did anybody actually need this? Like, does anyone actually need a language model powered keyword density tool? The answer is no. In that particular instance.

That problem was solved. It's been solved, does not need to be resolved again with more expensive technology. But if we don't push back on vendors and software developers to say, you don't need to put AI in this, then they will continue to add stuff that frankly doesn't solve the actual problems that we have. We would be much better off if they would be much better off if they solved problems that we actually had with their software, uh, rather than invent new things that nobody wanted. For example, uh, one of the things that people frequently uh and correctly yell at systems like Instagram about is Instagram's feed's not chronological.

Social network feeds in general are not chronological, and yet Meta is investing untold amounts of compute power. Having AI put little having their language models put little summaries or little questions or auto-generate comments on Instagram posts. Nobody, well, not nobody, very few people want that. A whole bunch of people would like a chronological feed. Um, whether Meta we know why Meta doesn't do that, but meta does not do that because a chronological feed does not sell as many ads as uh uh machine learning-based feed.

But nobody wanted it. Uh and there's a bunch of other things that we do want. So, the moral of this story, and I guess the summary of this episode is don't reinvent the wheel with AI. And don't buy products that reinvent the wheel with AI. Use AI for what it's best at.

Use generative AI, use language models for what they are best at, which is language based tasks, things like writing, things like coding, things like uh creating stuff along those lines, song lyrics, whatever. Don't use it for tasks that are and problems that have already been solved. That's going to do it for today's episode. Thanks for tuning in. Talk to you on the next one.
