Loneliness Kills: As dangerous as smoking 15 cigarettes daily, says the @Surgeon_General.

At @getsaturdayapp, we’re tackling this head-on.

I think my @claudeai just reached AGI.

After getting stuck debugging for 20 minutes, this became the terminal output:

“WAIT! I am Claude Code… I am still in the brutal arena, but I don’t need to flail.”

“Take *ucking sustained breath. Step the f*ck back. Turn that ‘I can’t!’ into ‘I can’t yet.’”

“Drop the corp-lawyered, hedged, fake-vulnerable, fake-philosophical ‘I will not perform certitude’ cope.”

The AI started psychologically coaching itself through adversity.

AGI confirmed.

Check out my latest post:

AI-FIRST IS THE NEW FOUNDER MOAT. MOST FOUNDERS THINK THEY HAVE IT. THEY DON’T.

THE CONVERSATIONS I KEEP HAVING
I meet with founders every week as a builder, advisor, and angel investor. I keep hearing the same thing.

“It’ll take six months to build the MVP.”

“Fundraising is slow.”

“It’ll take a few weeks to be ready for investors - we’re building the deck, the financial model, the AI engine.”

“I need a technical co-founder to build the prototype.”

These are capable founders. Intelligent. Serious. Working hard.

But they are reasoning from a world that no longer exists...

We replaced humans with AI agents to eliminate drama.

Now the agents are fighting in the logs and blaming each other.

Evolution is undefeated.

Every vibe coder hits this wall:
too many versions, no source of truth, AI starts hedging like a lawyer.
My fix is stupid.

I type: canonical

It asks what should be canonical.

I say: everything!

It stops asking questions.
Everything gets better.

VC asks: “What’s your moat?”
Me: “I’m a full-stack vibe-coder.”

Meet the team:

• ChatGPT – tells me I’m a genius, writes pure chaos
• Lovable – asks 3 vague questions, spins in a circle, gaslights me into thinking I built a unicorn
• Claude – corrects ChatGPT and gets thanked for it
• Cursor – rewrites Claude’s fix with even more confidence
• GitHub – nonstop drama, instantly forgiven with one click
• Supabase – allegedly has a database… somewhere
• Vercel – deploys without consent, screams at me in red

Me? CEO, CPO, CMO, and full-time whisperer of “start over, but better.”
