How much of "good engineering practices" exist because we're trying to make it easy for humans to work with the code?

Pick your favorite GoF design pattern. Is that they best way to do it for the computer or the best way to do it for the developer?

I'm just making this up now, maybe it's not the greatest example; but, let's consider the "visitor" pattern.

There's some framework that does a big loop and calls the visit() function on an object. If you want to add a new type, you inherit from that interface, put visit() on your function and all is well. From a "good" engineering practice, this makes sense to a developer, you don't have to touch much code and your stuff lives in it's own little area. That all feels right to us as developers because we don't have a big context window.

But what if your code was all generated code, and if you want to add a new type to do something that would have been done in visit(). You tell the LLM "add this new functionality to the loop for this type of object". Maybe it does a case statement and puts the stuff right in the loop. That "feels" bad if there's a human in the loop, but does it matter to the computer?

Yes, we're early LLMs aren't deterministic, and verification may be hard now. But that may change.

In the context of a higher-level language, y=x/3 and y=x/4 look the same, but I bet the generated assembly does a shift on the latter and a multiply-by-a-constant on the former. While the "developer interface", the source code, looks similar (like writing to a visitor pattern), the generated assembly will look different. Do we care?

I agree with all of those statements - I always told my wife that I'd get our kids a underpowered manual so that they're always busy rowing gears and can't text and drive.

But in the bigger picture, where does it stop?

You had to do manual spark advance while driving in the 30's

You had to set the weights in the distributor to adjust spark advance in the 70's

Now the computer has a programed set of tables for spark advance

I bet you never think of spark advance while you're driving now, does that take away from deeply understanding the car?

I used to think about the accelerator pump in a the carburetor when I drove one, now I just know that the extra fuel richening comes from another lookup table in the ECU when I press the gas pedal down, am I less connected to the car now?

My old Jeep would lean cut when I took my foot off the gas and the throttle would shut quickly. My early fuel injected car from the 80's had a damper to slow the throttle closing to prevent extreme leaning out when you take your foot off the gas. Now that's all tables in the ECU.

I don't disagree with you that a manual transmission lets you really understand the car, but that's really just the latest thing were losing, we don't even remember all of the other "deep connections" to a car that were there 50-100 years ago. What makes this one different? Is it just the one that's salient now?

To bring it back on topic. I used to hand-tune assembly for high performance stuff, now the compilers do better than me and I haven't looked at assembly in probably 10 years. Is moving to AI generated code any different? I still think about how I write my C so that the compiler gets the best hints to make good assembly, but I don't touch the assembly. In a few years will be be clever with how we prompt so that the AI generates the best code? Is that a fundamentally different thing, or does it just feel weird to us because of where we are now. How did the generation of programmers before me feel about giving up assembly and handing it over to the compilers?

I was having almost this exact same discussion with a neighbor who's about my age and has kids about my kids' ages. I had recently sold my old truck, and now I only have one (very old and fragile) car left with a manual transmission. I need to keep it running a few more years for my kids to learn how to drive it since it's really hard to get a new car with a stick now...or do I?

Is learning to drive stick as out dated as learning how to do spark advance on a Model T? Do I just give in and accept that all of my future cars, and all the cars for my kids are just going to be automatic? When I was learning to drive, I had to understand how to prime the carburetor to start my dad's Jeep. But I only ever owned fuel injected cars, so that's a "skill" I never needed in real life.

It's the same angst I see in AI. Is typing code in the future going to be like owning a carbureted engine or manual transmission is now? Maybe? Likely? Do we want to hold on to the old way of doing things just because that's what we learned on and like?

Or is it just a new (and more abstracted) way of telling a computer what to do? I don't know.

Right now, I'm using AI like when I got my first automatic transmission. It does make things easier, but I still don't trust it and like to be in control because I'm better. But now automatics are better than even the best professional driver, so do I just accept it?

Technology progresses, at what point to we "accept it" and learn the new way? How much of holding on to the old way is just our "identity".

I don't have answers, but I have been thinking about this a lot lately (both in cars for my kids, and computers for my job).

This works wonders. I did it accidentally. In March 2020 when my gym closed, I started working out every night in the garage. After a couple of weeks a neighbor who I only ever said "hi" to wondered by and asked if he could join since his gym was closed. After a while more showed up, and now I have like 12 people every day show up. One Friday someone brought a bottle of whiskey and we hung out after the workout and now weekly happy hours are a regular occurrence. The neighbors who don't workout stop by after the workout for happy hour. It's almost become expected and folks schedule their weeks around it so that they can be there for drinks in the evening. As a super introvert nerd, I never thought I'd be the center of community in my neighborhood.

This may just be me, but I hold the opposite view.

When I lived in a rural area with a few acres of property, I was much more social and engaged with my community.

Now I live at the edge of the city in a medium-high density townhouse area with no private outdoor space. Since I can never really get away from people and be alone, I also have no desire to go out and do things and engage with the community.

I think the variability is nice. If I can get home, relax, not have people around, have some private outdoor space, then I can recharge and have the energy to engage more.
