I've become kind of obsessed with how to get the cost of personal aircraft down. Example: A new Cirrus SR22 costs around $1.1 million and weighs 1,111 kg without fuel. Call it $1,000/kg. A Tesla Model Y (long range AWD) costs around $50k and weighs around 1,980 kg. Call it $25/kg.

Then you also need to design it to be mass manufactured. I think there is an opportunity with MOSAIC to build a $50k airplane that goes totally mainstream. Other people who are thinking along similar lines, assemble.

For one, type certification needs to go afuera. This is already happening with the MOSAIC rule for aircraft that qualify for that (basically, have a low clean stall speed).

The second thing required is market scale. You need simplified flight controls (allowed by MOSAIC) to expand the market for personal aviation so that new people enter the market so that you can sell many units and get economies of scale in manufacturing.

A Honda Civic EX costs $27k and weighs 1,650 kg, for $20/kg. An airplane is not more complex than a car, but it costs 40x as much per kg. What would it take to build an airplane for $25/kg?

I drove 8+ hours today, and then looked up how much a charter flight for the same route (local airport) would be. Under $6k round trip for 4 passengers in a PC-12. Not quite affordable but cheaper than I expected. If we had had more innovation in aviation over the last 50 years, it could work.

Posted on bird site: I want a simple chronological timeline without threading, and I want the app to save state about location within that timeline across relaunches and devices. I had that with Tweetbot, but then Twitter disabled third-party clients, and my experience has been worse since.

Walking my dog this morning, I saw a Lamborghini Urus parked on the street. I am completely baffled as to why anyone would buy such a thing. I get wanting a Lambo. A Lambo SUV feels like such a waste, though.

Thinking about the future of AT Protocol, it seems that at some point there will need to be subrepos, just like git has submodules. Like if I’m building a subprotocol that requires hosting a ton of video data, Bluesky itself may not want to host all of it, and a subrepo seems like a good solution.

Morning thought: Eastern philosophy (and some iconoclastic Western philosophers like Parfit) basically believes that personal identity is a myth. We are all contingent on everything else. It’s very hard to live like that. But what if we all turned the personal identity knob down by 10%? 20%?

Doing the thing with the kids where you play “Roxanne” and they have to do burpees every time they hear the word Roxanne. Everyone does this right?

Sweet. I’m going to write a script to block everyone that @mattyglesias.bsky.social blocks.

Bluesky@bsky.app

Important: Similar to your likes, your block list is public data! While users of the Bluesky app can’t easily find this list now, the data is public and enumerable at the protocol level. This means that third-party apps or clients can surface and display your list.

we are human and need sleep. so bear with as we implement blocks (a week or two? juggling), along with sandbox-mode federation to test it all out. if you code and want to help, apply for a job. you will work intensely hard with us, but you may help remake the social web. come if you want to ride.

what if i don’t want my blocks to be public? what do we do if an aggro server refuses to respect my block? we had to answer all these questions, about an architecture that was not settled. it was simply not possible on the time constraints we had with 3 engineers.

i block someone on my server. ok. where does that information get stored? just my server? then other servers don’t know to respect it. ok, i publish it then. what if the other server doesn’t listen? what if there’s services beyond servers? (there are)
