There's 3 trim levels. Flying is the top tier. They already publicly announced that.

> it was vapourware. Period, full stop.

What sad reaction to a real life flying car.


What was demonstrated was not flight.

Out of curiosity, how do you define flight? To me, I think the Roadster flew because it clearly maintained powered propulsion after leaving the ground. Sure, it only flew for a few seconds, but it's not far from the Wright Bros.' first flight.

Being able to take off from the ground. Not using a second system to vacuum its way up to a platform and then fall slowly.

This machine demonstrated zero ability to gain altitude in the air alone.


The Kickflip demo showed it taking off from the ground: https://www.youtube.com/watch?v=r5vsHHPVhJg

I don't think you watched the whole show. The third stunt was taking off from a stop to jump over some vehicles. So it did gain altitude in the air alone.

Well color me corrected. I’d probably quibble that this was a hop/jump the same way humans can jump but not fly, but I don’t have a strong definition at that point to argue for.

I’d need to go deep into something like being able to maintain altitude in the medium of air without positive impulse or something, but again, I don’t have a strong enough definition at this point.


Are you new? Flying concept cars have been around forever. It’s not a new thing.

the timeline we're in is various adjectives including sad. reality never hits how you envision when you're 10.

Out of curiosity, what is your sad P(>500 people owning a flying Tesla by 2030)?

Why does it matter? Did you ask the same question in 2007-8 when the first Waymo cars were on the streets for testing?

No.

It’s a cool concept car, and very impressive engineering. I don’t get why people hate on it so much.


I didn’t, because Waymo cars were proof of concept, not proof of wallet size.

It is very impressive engineering, just not very useful or ever going to result in any viable product. It’s a dead end. A waste of somebody’s engineering effort and talent for a one-time rich guy demo item. People hate on it because they get it.


Must surely exceed P(AI doom)

Zero. Maybe a dozen, non road legal ofc. And I'm not particularly sad about it. Sorry to disappoint.

Your so called grown up world sounds like the delusion neo-liberal free market thinking that got the West here in the first place.

It works fine for the most part, we have cheap chips (not right now, though) cheap parts of cars, cheap TVs, etc. That are manufactured in developing countries (helping them develop in the process) and designed in developed countries (where only this stuff is possible to design).

It just breaks down when bad actors go against reason for long enough, but the market also corrects for that changing supply chains.


Got the West where? Massively successful and prosperous?

Two generations and counting who can see that they are less successful and prosperous than their parents.

Would the Internet going away be world ending? Interesting to think about. I think it would be pretty damn devastating on the scale of Nuclear war but slightly more of a slow burner. At least with Nuclear war survivors can turn the Internet back on again afterwards.

Sounds more like OpenAI.

tl;dr why is it better than git?

I think this app is broken. Every time it refreshes it calls me a different name.

Chameleon?

Is that true? The loop is a branch.

The "go around" branch is obviously not completely avoidable (though unrolling helps). Branches inside the loop body sometimes are.

Who actually considers a loop a branch? A loop is a chunk of code that will be run N times depending on some evaluation that’s run before or after an iteration. A branch is a single decision which of several pieces of code to run, once.

> Who actually considers a loop a branch?

A loop contains a branch - keep looping or break. At least according to structured programming -- https://en.wikipedia.org/wiki/Structured_program_theorem.


> Who actually considers a loop a branch?

interesting question...

> A loop is a chunk of code that will be run N times depending

oh! turns out you do!


branchless for loop for funsies

  for (fn, n) = {
    stop = void (i) {}
    run  = void (i) { fn(i); go(i + 1) }
    go   = void (i) { *((i < n) * &run + (i >= n) * &stop)(i) }
    go(0)
  }
Or you could write all the implementations for each possible n and dispatch through a registry.

>Who actually considers a loop a branch?

The machine?


https://godbolt.org/z/rz8MxhdGd

Just a simple example, but the conditional branch occurs on line 14 of the generated assembly. It does a comparison (line 13) and then a conditional jump (jl, line 14).


> Who actually considers a loop a branch?

The CPU.


Yeah I was like what, is branching a matter of opinion??

> Who actually considers a loop a branch?

Anyone who started out programming in assembly languages


most people? i mean the condition in a for loop makes this pretty obvious

Usually yes, but if inside loop is even more branches. Also obviously wasteful when it's checking a computed condition.

Not categorically though: an infinite loop does not contain a branch.

It's just an unconditional branch but still a branch. Probably even not an unrollable one due to non-infinite memory.

If you wrote down any of your thoughts on the open Internet you are probably in some small - or possibly large, unattributed way, responsible for this result being possible.

Which is one reason I never really did. I probably should have but I always thought my attempts were too amateurish. Though I did manage to replicate some partial result papers that I didn't know about, lol. Writing openly would have saved me some years.

Did you feed OpenAI models with your insights though ?

What does that mean?

Tradies will buy poorly maintained houses and fix them up.

ChatGPT will tell everyone else (who cares to do it) how to do the same thing. It's not hard.

As a software guy who’s worked alongside trades for the past 15 years, ChatGPT can tell you some of the tricks but the know-how comes from hands-on experience. I’ve lost count of the tips and tricks I’ve picked up from watching and talking to those guys.

And sell them to... ?
