The ultimate goal is getting paid to be yourself. To solve problems you can't help but solve. To study what you can't pull yourself away from. To eliminate any work that does not challenge you creatively.

@Erdayastronaut Getting into YouTube shorts, eh? Looking forward to it!

I overheard this line that was so powerful by Jimmy Carr I felt obligated to share it:
"Suicide doesn't make the pain go away. It just shifts it from you to everyone who loves you."
Woof.

@samsheffer Congrats!
What do you think was the biggest unlock between that original tweet and today?

Mac search has been broken for 2 years, and nobody at Apple seems to care.

- I open spotlight search
- Type "calc"
- Calculator appears
- I hit return

But in the 0.2 seconds before I hit return, it swaps to a random file with the word "calc" in it somewhere. And I open a file I didn't want.

This happens to me every single day.

Very unbecoming of a $5T company whose customers are still obsessed with its products.

@stocktradernet Was surprised to hear this! Until the part about demand from China, of course.

Hate to say it, but I think FSD v14 Lite has some regression (2026.20.6.11 on my AI3 2019 Model 3).

It’s WAY too hesitant in some situations. Nearly got t-boned from it stopping in the middle of an uncontrolled intersection for a left-hand turn. And way too many brake stabs.

@DriveTeslaca Just installed 2026.20.6.11 on my 2019 Model 3 too! Having the button to start self driving from park is such an improvement!

The new development cycle in one image.

[Boris Cherny @bcherny]

As engineering, product, design, DS, etc. melt into a new kind of role, I was reflecting on what roles might look like in the future. For example, when I look at the Claude Code team I see what I think is five archetypes:

1. Prototyper: comes up with brand new ideas; churns out many ideas, most of which don't ship
2. Builder: quickly turns a prototype/idea into production-grade product/infra
3. Sweeper: cleans up the UI, simplifies the code and system, unships, optimizes performance
4. Grower: takes a product that has been built and iterates on it to improve Product-Market Fit
5. Maintainer: owns a mature system to make it secure, reliable, fast, and efficient as it scales

Many people span across 2 roles, and sometimes 3 roles. I also notice that these roles are not really tied to job function -- eg. across Anthropic, some designers match category 1, some 2, some 3; same for engineers, PM, DS.

A healthy team needs a mix of these, depending on the product:

- A product that is new and pre-PMF needs people that are strong at 1+2+3
- A product that is growing and has found PMF needs 2+3+4 and some 5
- A product that has strong PMF needs 3+4+5 and some 2

Maybe product roles of the future will look more like this, and less like the domain-specific roles of today?

Nothing makes you appreciate FSD more than driving 2 hours in traffic in a non-Tesla without it.

FSD has ruined other cars for me.

“We’ve done the analysis, reusable rockets aren’t economic.”

SpaceX makes reusable rockets economic.

“We’ve done the analysis satellite internet isn’t economic. The antenna alone is tens of thousands of dollars. The cost to manage a constellation that size, the radiation, the space hardened solar cost…”

Satellite internet appears to be a very good business with antennas in the $100 range.

“We’ve done the analysis, orbital data centers aren’t economic. The radiators, launch costs, the radiation, the solar…”

You are here.

@mattpocockuk Sounds a bit like the Claude superpowers /brainstorming skill, but on steroids. Anyone used both?

@cloggedDrain @JonBbC_TechGeek Yes, this exact scenario happened to me too many times! So I’ve stopped using it. Albeit, that’s with HW3 12.6.4

Of course, the prompt can be refined and modified to suit your own needs. I’ve found it helps with the reliability of some skills, and can reduce token usage and improve speed of often-used skills.

[Josh W @jwalskis]

If you constantly use skills/routines/cron jobs in Claude, OpenClaw, etc, here’s an easy way to reduce token usage and improve reliability of your skills:

Schedule the following for 4AM daily:

points and update the skill to use only the methods that actually succeeded.
Then improve only one skill/task with the highest impact (skip if you already modified it in the last ~72h). First back up the original.

hiring is impossible BECAUSE it's so easy to apply

finding a relationship is impossible BECAUSE new dates are a swipe away

getting into university is hard BECAUSE you can CommonApp apply to 50 at once

convenience is washing away friction that actually carried a lot of signal
