The long long tail of AI applications

First published on

Last year multiple companies asked me for advice. " We are evaluating this AI powered product, but do you think it makes sense at all? It seems a bit niche and we think ChatGPT might make this entire thing obsolete soon. " Long tail - credit to Wikipedia My answer so far has always been: "No, bare LLMs are not going to compete with this product." I think that people are failing to understand the distinction between different classes of AI companies. I see it like this: Foundational AI - creating models like GPT-4 (text), Sora (video) etc. Applied AI - using existing models to create smart applications. Note that there are also companies not focusing on AI - they will start lagging behind, let's forget about them ;) There are orders of magnitude  (!)   more companies that will deal with Applied AI than Foundational AI, and they will be very busy for decades to come. Here's why: To get the most out of LLMs, you have to ask the right questions. LLMs have acc...

I mean security is a good thing, but this seems a bit too simple? In fact, hollow marketing claims like that can make me a bit angry. In this post I'll help you understand what to make of statements like that...

Edit: since creating this post I've also created a video about this project on YouTube. See it below or jump straight into all the details below. Here's a very beautiful antique rotary phone. It's a Dutch PTT phone model called simply "1950" . But, what's this at the back? A USB-C port? A peek inside shows us some weird things! How did that LiPO battery get there? Ok let's quit the jokey intro, this was all me. I've had this phone for about 15 years and over the last couple of weeks I've converted into a fully functioning Bluetooth headset using an ESP32 microcontroller. In this post: - 1 - Features - 2 - Lessons Learned - 3 - Pictures and story!  of how it got made (scroll down!) but first... Does it work? This morning was the first Google meet I've used it in: A participant reported on the sound quality "I didn't know how much I missed the different sound quality! Beautiful. We could hear you very well, not distorted. I wish I record...
