about AI (including tech people), it is hard not to notice how unaware most people are of what&#8217;s going on; at the same time, I understand how challenging it is <a href="https://notes.lucasmuller.com/p/how-have-you-been-using-and-experiencing">for most to grasp</a>. Plus, the current communication stream noise is absurd.</p><p>In a nutshell, what most people don&#8217;t see, understand, or realize about where we are in the development curve of AI is the fact that the changes we are seeing (and will continue to) are associated with the inherent sheer number of operational knobs (technical and hyperparameters of <a href="https://aima.cs.berkeley.edu">deep learning architectures</a>) and the strategic levers available to play, experiment, expand, and advance, leading to more advanced features and capabilities. So the fact that things are changing this fast isn't a big surprise if you understand how many factors are at play at a time.</p><div class="captioned-image-container"><figure><a class="image-link
