Lots of new followers so thought I'd do an intro 🙂
This is me, without hat, in my garden, on a rainy morning in Manchester 🐝, UK
Been working in tech for 25 years - software engineer then various leadership roles. Nowadays I'm a product & tech leadership advisor, coach, consultant.

Software engineering is a hot mess right now. We'll get back to you when we've figured it all out, which may take some time.
In the meantime, be wary of people confidently proclaiming they've figured it all out, they haven't.
Looks like we're going to have to learn the hard way.

The Phoenix Architecture
Generative AI coding demands what we've always known: modularity, clear boundaries, disposable components. Principles that scaled human teams are now table stakes. Here, we make the implicit explicit

I've been using Claude Code for a lot more than just coding (thanks to @chrismdp.com) - a good guide for non-devs for how to get set up.

One thing in this I do agree on - the relevance of CS/SE degrees
Already many decades behind modern technologies & practices
Ofc learning fundamentals very important, more so even but only a small part of the gig
Like many, I never did a CS degree & self-teaching now vs late 90s...

Even in the punchcard and batch era, coding was not the main bottleneck with software delivery.

I keep seeing posts claiming GenAI means coding is no longer the bottleneck.
It never was.
I wrote this as something to point people to, showing many practitioners have been saying this for decades.

As dust settling on ChatGPT5.2 and Gemini 3, the pattern appears to be capability reallocation rather than general improvement.
Better scores on narrow reasoning and benchmarks, but trade offs elsewhere like consistency & hallucinations.

From fire and cooking, agriculture, to fossil fuels, the biggest jumps in human living standards came from unlocking more usable energy.
Any future industrial-revolution-scale shift will almost certainly involve a comparable change in energy availability, not information technology alone.

I’ve been trying to work out why new GenAI models don’t feel much different to me
GenAI operates through a narrow, lossy interface. Good at helping with slices of work, but real constraints sit elsewhere
Better models don't change the boundary. So it doesn’t really matter how “smart” models get

The industrial revolution broke hard limits. You could point at a train and say this could not exist before - people and goods moving in hours, not days.
GenAI = more like faster horses - better versions of what we already had: writing, code, analysis, planning
Useful, but not the kind of shift

Observation: I don't think AI having a habit of creating duplication in code is just a consequence of being trained on poor code. When I'm using it to support writing/documentation, it's constantly repeating and duplicating things.
