I wrote about AI in software engineering, and about making choices.

A longer and more nuanced follow-up to my viral toot from last week.

Two very senior engineers, pairing for over an hour, to figure out that a function call had its first two arguments in the wrong order.

I'm not sure what the moral of this story is. Maybe it's that stupid stuff will trip you up, no matter how experienced you are. Or that positional arguments were a mistake. Or maybe that meatbags weren't meant to code and we really do just need to hand it all over to the AI overlords.

@hanshuebner @flooper I explicitly called out Worse is Better, which is exactly what you are talking about. The original formulation was that Unix "won" because it was "worse", it was simpler, easier to port, etc. That whole dogma has morphed over time. During the SaaS boom worse-is-better meant ship MVPs to capture market and lock in users. Now that we're in the enshittify stage it means "drop quality and raise prices as much as the user will bear before churning", enabled by platform lock in. So yes, for some capitalist notion this is winning, it's certainly extracting value. It's a notion I wholeheartedly reject.

@hanshuebner @can seriously Hans, I am in no mood for this. Yes, the force of capital is overwhelming, and there's little that a bubble of old timers on the fediverse is going to do about it. We're all going to have to reckon with that and figure out what choices we have left. That's life under capitalism. The least we can do is speak our truth, and call things out for what they really are. At least we won't feel like we're the only ones who think this shit sucks, or who see it for what it really is. There's a reason I talk about hegemony. The defeatism only hastens the process.

It's clear that AI assisted coding is dividing developers (welcome to the culture wars!). I've seen a few blog posts now that talk about how some people just "love the craft", "delight in making something just right, like knitting", etc, as opposed to people who just "want to make it work". As if that explains the divide.

How about this, some people resent the notion of being a babysitter to a stochastic token machine, hastening their own cognitive decline. Some people resent paying rent to a handful of US companies, all coming directly out of the TESCREAL human extinction cult, to be able to write software. Some people resent the "worse is better" steady decline of software quality over the past two decades, now supercharged. Some people resent that the hegemonic computing ecosystem is entirely shaped by the logic of venture capital. Some people hate that the digital commons is walled off and sold back to us. Oh and I guess some people also don't like the thought of making coding several orders of magnitude more energy intensive during a climate emergency.

But sure, no, it's really because we mourn the loss of our hobby.

It is quite astonishing to me how much AI adoption is being driven by literal FOMO.

Devs don't want to miss the boat, lest they become obsolete. Not really doing it for you? That's a skill issue, try harder.

Managers/execs pushing AI through forced mandates, lest they fall behind the competition. Not getting the expected results? It's ok, we're learning. Push harder, set token quotas, do internal hackatons.

Policy makers and investors chasing the next growth engine. Do whatever it takes to stimulate their own local AI industry. Capture the market, returns will come later.

Tomorrow's St Patrick's day, but we've been chasing that pot of gold at the end of the rainbow for a while now.

I have some consulting capacity available the coming months. I have a proven track record of making tech teams more effective, through a combination of technical and non-technical work. I work around communication and documentation, dev experience, architecture, alignment between biz and the dev team, and software/product development process, as well as doing staff-level engineering work.

DMs are open! Ping me if you like to have a chat!
