Over the last week, I’ve used AI to, among other things:

• Write ~70kLOCs of integration and E2E tests for a codebase with hundreds of kLOCs and zero code coverage
• Have my PRs reviewed.
• Have AI address AI-generated PR comments.
• Debug product issues, GitHub Actions issues, and improve our observability.
• Research technologies and product categories to inform engineering decisions.
• Generate Anki cards for topics I’m studying using my Anki style guide.
• Create memorable D&D NPCs, create unique images for them, then turn them into 3D models for 3d printing.
• Learn Blender well enough to sculpt and slice those models.
• Build a Claude Code-like agent aware of my Obsidian vault to edit D&D synopses.
• Get coaching feedback on my communication style.
• Get useful comments on an important self-help topic involving spirituality, psychology, and engineering. I don’t know anyone I could currently talk about this topic.

As many have noted, even if AI progress stalled for 5+ years, it will take us a long time to max out the capabilities of what we already have.

TIL about fzf built-in history command, fc, that keeps track of when you issue commands and how long they take to complete. It’s critical info when I need it, but I regularly don’t need it and so far I had been printing timestamps as part of my shell prompt. Time to update my aliases.zsh:

alias h='fc -lt "%b %d %H:%M:%S"'
alias history="echo 'use h'"  # Reduce unnecessary keystrokes while we're at this

Prompt BEFORE:
