Why hasn't this happened already?

I'm willing to believe the hype on LLMs except that I don't see any tiny 1-senior-dev-plus-agents companies disrupting the market. Maybe it just hasn't happened "yet"... But I've been kind of wondering the same thing for most of 2025.

I think it has to get good enough to a point where humans are not the bottleneck for code review and course correction.

I guess the "velocity" multiplier is closer to 10x rather than the 1000x needed for true disruption capability.

"The LLM can write lines of code, sure, but can it be productive?" is, I think, the implied question.

I always say, "it's a prediction, not a promise."

  1. Take every single function, even private ones.
  2. Mock every argument and collaborator.
  3. Call the function.
  4. Assert the mocks were  called in the expected way.

These tests help you find inadvertent changes, yes, but they also create constant noise about changes you intend.

These tests also break encapsulation in many cases because they're not testing the interface contract, they're testing the implementation.

Juniors on one of the teams I work with only write this kind of tests. It’s tiring, and I have to tell them to test the behaviour, not the implementation. And yet every time they do the same thing. Or rather their AI IDE spits these out.

You beat me to it, and yep these are exactly it.

“Mock the world then test your mocks”, I’m simply not convinced these have any value at all after my nearly two decades of doing this professionally

Your first three paragraphs are sound.

But surely the problem with the final paragraph is the transition? Assuming the old style of vehicle remains on the road, then my lightweight one is at risk of being crushed. Only a niche minority would choose that (as a cargo bike owner, I'm also one, but I recognise most are not, with good reason.)

Unless we built a whole separate infrastructure.... We already see a lot of electric scooters using cycle lanes.

Yes. More separated lanes leads to increased usage. We need to do this anyway.

What did the cops say?

They followed them to school and told the teachers that someone called the police for escort.

There's nothing illegal about this and nobody got in trouble but it still sucks.

You are lucky they called the police and not CPS.

CPS have nearly unlimited ability to fuck with your family, whereas police generally can't fuck with you without probable cause a crime has occurred. There is no such process or due process with child protection services as breaking apart families and tossing kids into the abusive foster system is considered 'civil.' CPS doesn't require a criminal law be broken to take action and can declare weaknesses in your parenting for things as simple as dirty dishes in the sink or your refrigerator empty because you're at the end of your grocery cycle.

I realised this year that all the arguments I'd ever heard for shifting the hour (lighter mornings in winter help kids get to school alive and help farmers work) were arguments for GMT itself, not for BST.

So why don't we just have GMT year-round? It's kinda fun to have sunset at 2130 in June but is it really so important?

I don't think it has anything to do with age but with the rate of new experiences.

Take a year off work to travel the world and you'll find your subjective sense of time passing slows right down.

Does it matter though? Does it matter how many experiences you collect? You can't take them with you. Better to develop relationships that can be a source of joy (I imagine. I have not done that).

It may not matter in any objective sense, or even a subjective one.

But if you want your sense of time passing to slow down, increasing the rate of new experiences might be one way to get there.

if you want your sense of time passing to slow down, go sit in an empty silent room with nothing to do

It's a great paradox. What you say is true, but it is also true that a period of life with more novel experiences will also appear to pass more slowly.

I mean, you can’t take the relationships with you either.

Do whatever makes you happy.

You can though. Pharohs were interred with their living concubines.

Visual Basic didn't exist in the 80's. First release was 1991.

Thanks for reminding me about Rational Rose though! That was a nostalgia trip

Man, these days I'm lucky if I get the century right.
