> Bullshit, no it can't

I mean, this isn't crazy. In fact, it's already been done. Ever heard of McMurtry? (https://mcmurtry.com/). They're notorious for exactly this - using fans to provide extreme downforce (urr... upforce if you're hanging upside down?).

> In flight?

Did you see the stunt where it literally flew over vehicles? I mean, maybe it's a bit closer to a controlled super-leap like the original Superman, but... yeah, my personal reaction to that was more "holy shit" than "well, that's not flying".

As near as I can remember, my first real programming experience was when I was eight years old, writing basic programs on an Apple IIc at school in 3rd grade. (I was too poor to afford my own computer until my senior year of college). It was awesome.

I have never found computers disappointing, and I have spent most of my career/life learning about them - from processor design through to distributed systems. Mostly I've been disappointed in the disparity between the number of interesting things I'd like to do, and the number of lifetimes I have available to me.

Different strokes for different folks, I guess.

It'd definitely be my preference to lean on existing law where it makes sense (law is already too complicated). Unfortunately, IANAL, so I don't know what makes the most sense. Whatever we have doesn't seem to be doing a great job against the mass spread of cameras and abuse.

Yeah, as a human race, we've clearly reached the technological era where deep, ubiquitous surveillance is both technologically and economically feasible. For a few years now, I've been thinking we need a constitutional amendment to restrict the mechanisms, deployment, and use of mass automated surveillance.

Human beings don't empathize well with situations nor people they never have to personally face. That's a well-lit path to fascism. We're one step closer to 1984.

This is how pedagogy works. You must simplify something.

For a Tesla, the estimates are around $2K. For a Waymo, the same estimates are ~$25K (down from $125K!!!). There's not a clear timeline for Waymo-style kit at a price consumers can afford and in a form factor they'd accept.

(FWIW, the business story for Waymo has never been about its hardware making its way to consumers. It's always been about whether Waymo continues to run its own taxi service or leases out hardware and operations to other taxi businesses).

Studies seem to favor waist to height over waist to hip for a stronger correlation to better outcomes.

Nah, as titzer said, it's really about general-purpose code being branchy (a good match for CPUs) vs numeric code being heavily parallelized and non-branchy (a good match for SIMD/GPUs). Only a small subset of very specific languages / instructions target the latter (e.g. CUDA and SSE4).

Maybe you drive into flood waters, but I don't. That's not a difficult skill to pull off.

We're still in the early days of self driving cars, and as much simulation and miles as they have, they're still constantly getting exposed to real world conditions that are new to them. The world is dynamic, so this will always remain true.

It remains to be seen where we'll converge on capability, incident rate, and acceptance.

My most enjoyable and productive experiences with AI so far have looked more like pair-programming than agent-based vibe coding. That is to say, I care about the details, and I want to read, understand, edit, and curate the codebase. I find that if I'm not limiting AI to relatively small enhancements per request-review cycle (100 or so LOC), then when things inevitably go off the rails, I'm in a deep hole that takes a long time to climb out of.

I haven't tried out Junie yet, but the concept seems pretty compelling to me. I want a good IDE for the language I'm using, and I'd like an AI that's well integrated and trained on delegating to it for algorithmic/deterministic transforms (e.g. IDE-driven refactorings).

They take about the same time as with an ICE. I stop and charge for 20m whenever I need a restroom break or some food (every couple hours or so). My car generally goes longer without stopping than I do.

If you're stopping often or long, something is wrong with your setup.

> I like Teslas a lot, but gave you ever been on a road trip in one? It's pretty brutal.

Maybe 50 road trips? Usually hundreds of miles, with the longest at 1000mi. Literally the easiest road trips I've done in my life.

I routinely traverse Monteagle with no substantive loss in efficiency. Sounds like something goofy with the mach-e?

I just drove 100mi in freezing temps (around 25F) at mostly interstate speeds (70+) mph. I completed my trip around 95% of EPA. Maybe a function of the quality of your EV.

I know congestion can be an issue at some sites, but I have never waited in line to charge in seven years of EV ownership.

In addition, for superchargers, you can see real-time stall availability, so if a particular site was crowded, you could just opt for the next. (Easy enough to do since there are so many).
