For those old enough to remember the Iraq/Afghanistan wars, with about 93 million people in them combined, they cost ~$8 trillion in today's money.
Iran also has 93 million people, and the war there could cost the same over the next 20 years.

AI^2: writing scripts and plugins so that AI prompts are programmatically produced and monitored.
Your CLI AI is running other AIs and monitoring those.

The widespread use of AI has led to expectations for best-of-breed solutions that far exceed productivity gains, meaning major tasks can take much longer.

Sureal moment: I told Codex the way /prompt worked wasn't right, and now it's looking through the ~/.nvm Codex code to figure out why

Yesterday, I was reminded that AI creates new classes of bugs. Gemini 3.0 Pro (preview) CLI kept “hallucinating” my config as code edits. Too much AI gap-filler kills determinism – we need Codex/Claude-style smart glue, not opaque agents. www.linkedin.com/feed/update/...

Tip for AI CLI: ask it to suggest topics to research to fix a problem, get a chat AI to do the research with web search, and paste the results into the CLI, save it to an adoc|md for future reference

A test that never failed doesn't add much value. Ask an AI to write a failing test, and it will write a broken test.
The solution I have found is:
1. Ask it to find/fix a bug and write a test to exercise it
2. Keeping only that test, check it fails without a fix
3. Write the fix

Don’t Talk English to Your LLM Just because LLMs are eloquent in natural language doesn’t mean that we should always communicate with them in it.

"Much of the most valuable Gen AI usage will grow out of existing business applications, rather than be wholly new. These applications will draw on existing domain models and infrastructure, and be more robust and useful as a result."

I find AI is more useful as a simulated developer user of the software.
It doesn't find bugs as often as it stumbles on usability issues.

The AI boom isn’t just about algorithms — it’s about money, power, and a race to build infrastructure on a scale we’ve never seen before

While Generative AI can increase the overall volume of documentation and code, in terms of curated and validated release content, the increase might only be +20%. The following represents the number of lines of ~6 months of work on similar projects, both before and after using AI.

The human developer’s role is still central. Understanding the problem, ensuring quality, and making architectural decisions remain human responsibilities that AI can’t shoulder
