    Sure. In my opinion, however, the overall context of the image does imply the jaguar enjoys similar effects to those clearly requiring the presence of DMT, as that is what is most people commonly associate with ayahuasca.

    It’s a bit of a “look at all those animals getting high, this jaguar is even talking to machine elves in the 19th dimension” kinda thing, where - if I remember correctly - they actually consume the leaves for digestive purposes.

    Again, the leaves do have an effect, e. g. they apparently act as an SSRI (that’s how common antidepressants work) and we can’t be absolutely sure about their effect on cats (catnip certainly has some effect on cats we don’t readily enjoy), so I can’t dismiss the notion of jaguars seeking them out for that reason as well.

    Jaguars actually eat the leaves of b. capii, which acts as a MAOI in the Ayahuasca brew.

    While there is some discussion that the harmala alkaloids in b. capii might also be slightly psychoactive in high doses, the actual main compound in Ayahuasca is DMT, which is certainly very psychoactive, but not bioavailable when consumed orally without a MAOI. Unless the jaguars have figured out how to combine the two and/or brew ayahuasca, I strongly doubt that’s their intention and that they’d get comparable effects.

    I think the idea stems from the BBC show Weird Nature showing a jaguar eating yage leaves in episode 6, “Peculiar Potions”.

    I’m not really sold on how well that content was researched.










  • I think you’re falling into a bit of a trap here: perfect is the enemy of good. Not everything has to be automated, instead of growing pains, there can also be gains.

    Remember, we are currently aiming to get these vehicles on the road, alongside regular drivers. They use sensors and computer vision to read street signs, detect people etc., all with the reaction speed of a machine. What if the in-between product is simply a better driver with faster reaction times? That is the current goal, really - no one wants to automate everything, simply because that wouldn’t be feasible anytime soon.

    Yes, again, we’re not there yet and these things are far from perfect. But let’s first just aim to get them good enough, and then maybe just a little better than your average driver.

    As for the your proposed business model: we have capable drivers now, why do these business models don’t exist right now? Why is there no fast lane that allows me pay to get to my destination faster? What would the technology of driverless cars introduce that would enable these regulations?


  • It’s not about everything being automated. We also have to differentiate between early incarnations of autonomous vehicles and the desired, final state.

    A manual override will of course be part of early models for the foreseeable future, but the overall goal is for the machine to make better decisions than a human could.

    I don’t have any quarrel with life or death decisions being made by a machine if they have been made according to the morals and ethics of the people who designed the machine, and with the objective data that was available to the system at the time, which is often better than what would be available to a human in the same situation.

    It’s the interpretation of said data that is still not fully there yet, and we humans will have to come to terms with the fact that a machine might indeed kill another human being in a situation where acting any different might cause more harm.

    I don’t subscribe to the notion that a machine’s decision is always worth less than the decision of another entity participating in the same situation, just because it so happens that the second entity happens to be a human being.


  • Yes, you probably are. Please don’t forget that the current available technology constantly improves, and that we actually don’t see any good examples of self - driving cars that much - the most prominent displays are from Tesla, and they arguably build the worst cars we’ve seen since Ford came up with the assembly line.

    The technology used in autonomous vehicles, e. g. sensors, have been used in safety critical application for decades in other contexts, and a machine is capable of completely different reaction times. Also, if autonomous vehicles cooperate in traffic sticking to their programmed behavior, observing traffic rules etc., you will get less reckless driving, with traffic flow becoming more deterministic. These benefits will particularly increase once self-driving cars don’t have to share the road with human drivers.

    I would always trust a well-engineered, self-driving car more than one driven by a human.

    Disclaimer: I used to work on these things in a research lab. Also, we’re not quite there yet, so please have a little patience.
