Now I want to talk about how they're selling AI. The growth narrative of AI is that AI will disrupt labor markets. I use "disrupt" here in its most disreputable, tech bro sense.
The promise of AI – the promise AI companies make to investors – is that there will be AIs that can do your job, and when your boss fires you and replaces you with AI, he will keep half of your salary for himself, and give the other half to the AI company.
That's it.
That's the $13T growth story that MorganStanley is telling. It's why big investors and institutionals are giving AI companies hundreds of billions of dollars. And because they are piling in, normies are also getting sucked in, risking their retirement savings and their family's financial security.

What to try first?
Run Claude Code in a repo (whether you know it well or not) and ask a question about how something works. You'll see how it looks through the files to find the answer.
The next thing to try is a code change where you know exactly what you want but it's tedious to type. Describe it in detail and let Claude figure it out. If there is similar code that it should follow, tell it so. From there, you can build intuition about more complex changes that it might be good at. [...]
As conversation length grows, each message gets more expensive while Claude gets dumber. That's a bad trade! [...] Run
/reset(or just quit and restart) to start over from scratch. Tell Claude to summarize the conversation so far to give you something to paste into the next chat if you want to save some of the context.

The Unexpected Effectiveness of One-Shot Decompilation with Claude
Chris Lewis decompiles N64 games. He wrote about this previously in Using Coding Agents to Decompile Nintendo 64 Games, describing his efforts to decompile Snowboard Kids 2 (released in 1999) using a "matching" process:The matching decompilation process involves analysing the MIPS assembly, inferring its behaviour, and writing C that, when compiled with the same toolchain and settings, reproduces the exact code: same registers, delay slots, and instruction order. [...]
A good match is more than just C code that compiles to the right bytes. It should look like something an N64-era developer would plausibly have written: simple, idiomatic C control flow and sensible data structures.
Chris was getting some useful results from coding agents earlier on, but this new post describes how a switching to a new processing Claude Opus 4.5 and Claude Code has massively accelerated the project - as demonstrated started by this chart on the decomp.dev page for his project:
Here's the prompt he was using.
The big productivity boost was unlocked by switching to use Claude Code in non-interactive mode and having it tackle the less complicated functions (aka the lowest hanging fruit) first. Here's the relevant code from the driving Bash script:
simplest_func=$(python3 tools/score_functions.py asm/nonmatchings/ 2>&1) # ... output=$(claude -p "decompile the function $simplest_func" 2>&1 | tee -a tools/vacuum.log)
score_functions.py uses some heuristics to decide which of the remaining un-matched functions look to be the least complex.

If you work slowly, you will be more likely to stick with your slightly obsolete work. You know that professor who spent seven years preparing lecture notes twenty years ago? He is not going to throw them away and start again, as that would be a new seven-year project. So he will keep teaching using aging lecture notes until he retires and someone finally updates the course.

TIL: Subtests in pytest 9.0.0+
I spotted an interesting new feature in the release notes for pytest 9.0.0: subtests.I'm a big user of the pytest.mark.parametrize decorator - see Documentation unit tests from 2018 - so I thought it would be interesting to try out subtests and see if they're a useful alternative.
Short version: this parameterized test:
@pytest.mark.parametrize("setting", app.SETTINGS) def test_settings_are_documented(settings_headings, setting): assert setting.name in settings_headings
Becomes this using subtests instead:
def test_settings_are_documented(settings_headings, subtests): for setting in app.SETTINGS: with subtests.test(setting=setting.name): assert setting.name in settings_headings
Why is this better? Two reasons:
I had Claude Code port several tests to the new pattern. I like it.
