Writing code is cheap now

Autolands absolutely do exist.

> Code has always been expensive. Producing a few hundred lines of clean, tested code takes most software developers a full day or more. Many of our engineering habits, at both the macro and micro level, are built around this core constraint.

> At the macro level we spend a great deal of time designing, estimating and planning out projects, to ensure that our expensive coding time is spent as efficiently as possible. Product feature ideas are evaluated in terms of how much value they can provide in exchange for that time - a feature needs to earn its development costs many times over to be worthwhile!

Maybe I am spending my life working at the wrong corporations (not FAANG/direct tech related), but that doesn't match at all my experience. The `design` phase was reduced to something more akin to a sketch in order to get faster iterating products. Obviously that now, as you create and debate over more iterations, the time for writing code is increased (as you built more stuff that is discarded). What is that discarded time used for? Well, it's the way new people learn the system/business domain. It's how we build the knowledge to support the product in production. It's how the business learns what are the limits/features, why they are there, what they can offer, what they must ask the regulators etc.

Realistically, if you only count the time required to develop the feature as described, is basically nothing. Most of the time is spent on edge-cases that are not written anywhere. You start coding something and 15m in you discover 5-10 cases not handled in any way. You ask business people, they ask other people. You start checking regulation docs/examples, etc. etc. Maybe there are no docs available, so you just push a version, and test if you assumptions are correct (most likely not...so go again and again). At the end of this process everyone gains a better understanding on how the business works, why, and what you can further improve.

Can AI speedrun this? Sure, but then how will all the people around gain the knowledge required to advance things? We learn through trial and error. Previously this was a shared experience for everyone in the business, now it becomes more and more a solitary experience of just speaking with AI.

Scathophagidae are flies that really like eating shit. We know how to cheaply produce massive amounts of shit.

But that doesn't mean we solved world hunger. In the same way, AIs churning out millions of lines of code doesn't mean we have solved software engineering.

Actually, I would argue that high LOCs are a liability, not an asset. We have found a very fast way of turning money into slop, which will then need maintenance and delay every future release. Unless, of course, you have an expert code reviewer who checks the AI output. But in that case, the productivity gains will be max 10%. Because thoroughly reviewing code is almost the same amount of work as writing it.

If writing code is cheap now why is there so much money involved?

I don’t think we can expect all workers at all companies to just adopt a new way of working. That’s not how competition works.

If agentic AI is a good idea and if it increases productivity we should expect to see some startup blowing everyone out of the water. I think we should be seeing it now if it makes you say ten times more productive. A lot of startups have had a year of agentic AI now to help them beat their competitors.
