I know this has been widely discussed and agreed upon by virtually everyone, but the fact that Siri is still so dumb in Q2 2026 is insane to me.

I just asked how hard it’s raining to see if I need an umbrella on my way to PT and it responds with, “Yes, it appears to be raining.”

So now I'm soaked, and Tim Apple is about to get quite the email.

Vibe coding with Bolt is the realization of a 10 year dream of mine as a non-technical PM.

I’m completely unshackled from design/eng gatekeepers. Now I create real software that enables the team to discover the right solutions before we actually build in our real app and ship.

I decided that I want to do most of my strategic thinking on a plane.

As a smug European, I definitely used to think that Celsius is just a superior scale for measuring temperature. After 21 years in North America, though, I definitely concede that Fahrenheit is simply better and more intuitive for temperature.

Many people chase wealth, status, and achievement because progress is easy to measure, failing to realize that the gains that count the most are the hardest to count.

Got the chance to watch this and wow this is something to see. It demonstrates in no uncertain terms how politics can be so brutally divisive yet also make possible the rise of dark horse candidates with a forceful message of unity and hope. https://t.co/Gv0sUxk9S5

[Harness @HarnessWealth]

As our clients at companies like @DoorDash, @Airbnb @PalantirTech and others prep for #IPO or direct listings, we've been getting questions on what decisions they should be making before and after a major liquidity event.

Here are the big three:
