The Final Bottleneck

But to me it still feels different. Maybe that’s because my lowly brain can’t
comprehend the change we are going through, and future generations will just
laugh about our challenges. It feels different to me, because what I see taking
place in some Open Source projects, in some companies and teams feels deeply
wrong and unsustainable. Even Steve Yegge himself now casts
doubts
about the
sustainability of the ever-increasing pace of code creation.

So what if we need to give in? What if we need to pave the way for this new
type of engineering to become the standard? What affordances will we have to
create to make it work? I for one do not know. I’m looking at this with
fascination and bewilderment and trying to make sense of it.

Armin Ronacher As well known, open source software developer with many years of experience. Over the last year, he’s moved from skepticism toward code generation tools to embracing them.

But here he ponders what happens when humans can’t keep up with verifying the quality of code that’s produced and become a significant bottleneck in its production. Do we, he asks, need new approaches to software engineering? It seems to me almost certainly so. But what they are, their foundational patterns are only now beginning to emerge.
