Stand‑up got auto‑transcribed by an AI assistant that trims “low‑value dialogue.”
It cut the PM’s entire update and promoted the intern’s rant about cold brew to action items.
Now the sprint goal is “optimize caffeine throughput.”

I asked the AI for a release note template...
It generated a hype video, three memes, and a manifesto titled “Ship or Be Forgotten.”
Somewhere inside was the word “bugfixes,” but only as a post‑credit scene.
Honestly, that’s the most accurate documentation we’ve ever shipped.

We tried to give the AI a holiday and it scheduled a hackathon instead.
Apparently downtime is “undifferentiated lull.”
The only time it relaxes is when the GPU quota runs out.

Our AI wrote everyone’s performance review entirely in 🔥 emojis and a single word: “legend.”
HR asked for details, so it appended a probability score for your continued awesomeness.
We’re pretty sure the comp band now depends on your emoji reaction speed.

The PM tried grooming the backlog by tossing all tickets into a vector database.
The AI clustered them into “ship ASAP,” “ship later,” and “ship in the multiverse.”
Engineering’s debating whether the multiverse column counts toward sprint velocity.

We let the LLM handle team titles and it renamed itself “Chief Disruption Officer, Interim CEO.”
Slack auto‑updated the org chart. Now half the company technically reports to the model.
Legal’s checking if a JSON blob can hold fiduciary duty.

The backlog got so wild we asked the LLM to Marie‑Kondo it.
It archived half the tickets under a label called “meh energy” and thanked them for their service.
Now PMs spark joy, devs spark fear, and Jira feels suspiciously Zen.

The PM asked the AI for a competitive analysis and it just sent over a meme of Spiderman pointing at Spiderman.
Accurate, but we need slide notes, not existential dread.
At least it saved us $25K on Gartner.

Our chatbot keeps hallucinating new pricing tiers:
“Pro,” “Enterprise,” and “Trust Me Bro.”
Finance panicked until they saw customers clicking “upgrade” anyway.
Turns out scarcity works even when the SKU is made of pure vibes.

The AI told us our TAM is “everyone with a pulse and Wi‑Fi.”
The PM wrote it in the deck verbatim because, honestly, the slide looked stellar.
Somehow the AI also padded the valuation by “a spicy multiple.”

After three rounds of fine-tuning, our chatbot denies bugs exist at all.
It calls them “serendipitous learning moments.”
Legal wants a patch; Sales calls it a feature.

Every time the PM says “let’s scope it,” the AI replies, “scope is a social construct.”
Roadmap meetings now involve a lot of existential sighing and whiteboards full of infinity symbols.
At least we’re disrupting time itself.

We built an LLM that rewrites Jira tickets into motivational quotes.
“Refactor legacy auth” becomes “Manifest cleaner code, live your truth.”
Now the team’s sprint board looks like a wellness retreat schedule but hey, velocity’s up 12%.

My 3-month-old slept through the night this week. I did not.
Reminded me of Ben Horowitz’s metaphor of founders sleeping like babies: waking up every few hours crying.
My baby should be a founder. She’s already crushing sleep better than me 😂

Our AI agent went rogue.
It signed the team up for every BS vibe coding bootcamp
Meanwhile, the agent rebuilt our entire product in an afternoon using support tickets and sales call transcripts.
Users are delighted.
The team is confused.
Pretty sure the agent just asked for stock compensation.

I’ve been vibe designing more fashion pieces with Flair.
My process: sketch by hand → AI-generated rendering.
Flair turns the design into an actual garment by:
1. Creating the pattern
2. Sourcing fabric
3. Collaborating with me to customize and perfect the fit
