  • This is truly a terrible accident. Given the flight tracking data and the cold, winter weather at the time, structural icing is likely to have caused the crash.

    Ice will increase an aircraft’s stall speed, and especially when an aircraft is flown with autopilot on in icing conditions, the autopilot pitch trim can end up being set to the limits of the aircraft without the pilots ever knowing.

    Eventually the icing situation becomes so severe that the stall speed of the ice-laden wing and elevator exceeds the current cruising speed and results in a aerodynamic stall, which if not immediately corrected with the right control inputs will develop into a spin.

    The spin shown in several videos is a terrifying flat spin. Flat spins develop from normal spins after just a few rotations. It’s very sad and unfortunate that we can hear that both engines are giving power while the plane is in a flat spin towards the ground. The first thing to do when a spin is encountered is to eliminate all sources of power as this will aggravate a spin into a flat spin.

    Once a flat spin is encountered, recovery from that condition is not guaranteed, especially in multi-engine aircraft where the outboard engines create a lot of rotational inertia.

    It took Hawking minutes to create some responses. Without the use of his hand due to his disease, he relied on the twitch of a few facial muscles to select from a list of available words.

    As funny as it is, that interview, or any interview with Hawkins contains pre-drafted responses from Hawking and follows a script.

    But the small facial movements showing his emotion still showed Hawking had fun doing it.



  • I am a pilot and this is NOT how autopilot works.

    There is some autoland capabilities in the larger commercial airliners, but autopilot can be as simple as a wing-leveler.

    The waypoints must be programmed by the pilot in the GPS. Altitude is entirely controlled by the pilot, not the plane, except when on a programming instrument approach, and only when it captures the glideslope (so you need to be in the correct general area in 3d space for it to work).

    An autopilot is actually a major hazard to the untrained pilot and has killed many, many untrained pilots as a result.

    Whereas when I get in my Tesla, I use voice commands to say where I want to go and now-a-days, I don’t have to make interventions. Even when it was first released 6 years ago, it still did more than most aircraft autopilots.


  • I’m an AI researcher at one of the world’s top universities on the topic. While you are correct that no AI has demonstrated self-agency, it doesn’t mean that it won’t imitate such actions.

    These days, when people think AI, they mostly are referring to Language Models as these are what most people will interact with. A language model is trained on a corpus of documents. In the event of Large Language Models like ChatGPT, they are trained on just about any written document in existence. This includes Hollywood scripts and short stories concerning sentient AI.

    If put in the right starting conditions by a user, any language model will start to behave as if it were sentient, imitating the training data from its corpus. This could have serious consequences if not protected against.




  • This is done by combining a Diffusion model with ControlNet interface. As long as you have a decently modern Nvidia GPU and familiarity with Python and Pytorch it’s relatively simple to create your own model.

    The ControlNet paper is here: https://arxiv.org/pdf/2302.05543.pdf

    I implemented this paper back in March. It’s as simple as it is brilliant. By using methods originally intended to adapt large pre-trained language models to a specific application, the author’s created a new model architecture that can better control the output of a diffusion model.

    A lot of people in this situation have already tried everything, and they are complaining on the internet because they feel like there is nothing else they can do. Most people won’t even complain about it with their friends. I know I didn’t until one day I got drunk camping. That was the trigger for me to do something about it, because it was clearly eating away at me.

    I had many conversations with my wife following that, and how much our sexless marriage really bothered me, but that I am still completely and totally in love with her. We don’t have kids, so there’s not anything keeping us together. We agreed to an open relationship with our rules, and each of us has a veto which could stop the arrangement at any time. We are still completely committed to one another and love spending time together. Things haven’t been better, now when I think about being with another woman, I don’t need to feel guilty about it.

    And I think this is the natural state of humanity. Everyone needs a long-term partner for stability and to care for one another, but people always felt the need to cheat as well. Monogamy is as core to our DNA and survival as is Adultery. But because we’ve talked about it, there is no sneaking around necessary, no lying. We are completely honest with each other on everything.


  • The same argument could be said for an apartment building too. We need to collectively realize that Single Family Houses are a luxury that most of us will never see in our lifetimes. Our grandparents were able to enjoy them at low prices because the US had half the population it does today.

    Restrictive building codes that only permit building SFH is the cause of our housing shortage and not short term rentals that consist of 0.2%-1% of all dwellings.


  • At it’s core, this is the root cause of the housing crisis. We do not have enough supply. The amount of Airbnb’s that exist is extremely miniscule and the targeting of Airbnbs is an intentional distraction tactic.

    Depending on the source, 1% to 0.2% of all dwellings are listed for short-term rental in the US. That’s crazy small and has very little impact on housing prices overall.

    The fact of the matter is that Single Family Homes are an incredible luxury that our parents and grandparents were able to enjoy when the country had half as many people as it does now. It is no longer sustainable to expect a SFH in the US, and the American public continuing to cling to that dream and restrictive zoning practices are really what is driving up prices.

    If you want an affordable house you will need to move to a rural area where land and labor are cheap. If you want to live near any reasonably sized city, you better be upper middle class to even think about buying a SFH.
