Ive seen the analogy that AI is to biological intelligence as airplanes are to birds. I think that’s appropriate. And furthermore, we find that when we make better airplanes they don’t become more bird-like. We are optimizing for something that biology didn’t optimize for. I think AI will be similar

Just as the field of ML has become a distinct discipline from statistics (but have a lot of overlap… it’s a continuum), I feel like there’s a new field of AI that is diverging from ML. Again they have a lot of overlap, but the study and use of these massive AI models feels like a new thing

It seems that computational work is undergoing two simultaneous transitions that resemble transitions of the past: 1) The transition from coding in a programming language to describing via natural language (AI writes the code) resembles the transition from machine code to programming languages.

When trying to reason or prove something in a rigorous mathematical way as it relates to a real-world problem, most of the work seems to lie in developing the right formalism. Once the formalism is established, the math becomes "disinhibited" and flows more effortlessly.

Cells don’t interact in just 2 dimensions—so why study them that way?
In 2D spatial analysis, critical interactions between cell types can be underestimated, leading to distorted biological insights.

Cells transport proteins in membrane vesicles.
These vesicles are formed by self-assembled exoskeleton.
The exoskeleton scaffolds are cuboctahedrons made of proteins.

Good software engineering requires understanding human cognition to reduce cognitive load. I think all the fancy paradigms are just ways to accomplish this.

Cognitive load is what matters
There are so many buzzwords and best practices out there, but let's focus on something more fundamental. What matters is the amount of confusion developers feel when going through the code.

As someone new to image analysis, I recently came upon this perspective that seems trivial, but is actually important: A pixel is a "point sample" and not a little square. A pixel is a data point, sampled from the world, like any other data point would be. pages.graphics.cs.wisc.edu/559-f14/2014...
What is a Pixel? (and what is a point sample)
When we talk about image-based graphics, we talk about it being a regular collection (usually a grid) of samples (or pixels). It’s time to be a little more precise about this. The term pixel is (I’m t...
