You'd have to have some incredible rapid attrition to have the median be above the average. Any tech company that left skewed would be considered a disaster by pretty much anyone.

The problem is that if it was 8 in 10 suggestions or even 8 in 20, then yes, terrible. On the other hand, if it was 8 needles in a haystack of garbage, at some point you do, in fact, need to tell people to STFU so you can work.

Every single engineer I know who went to Amazon except one lasted under 3 years and to this day, often ten+ years later, they all will mention how much they hated it.

The one exception is an engineer who stopped engineering, switched into product, and transferred to China to hit on the women there.

Some Amazon practices actually sound great to me (short documents, read before the meeting) but so many things just sound needlessly, relentlessly cheap.

PA Semi was kind of an interesting acquisition. The team was definitely very skilled, but there are always gotchas. Before the acquisition happened we were on their receiving end of their dual core PPC and it was not great at all. We had a lot of issues with board bringup, power, and heat. More errata than I've ever seen. We eventually had to went with x86 for the project instead, which was more performant and certainly a lot easier overall at the time.

I had previously encountered some of that team with the SiByte MIPS in an embedded context, I know they were highly skilled, they had tons of pedigree, but PA Semi itself was a strange beast.

The one for me which was quite surprising is how recent grasses are. Grass is 110M or so year old, but grasses as we know them - the plains, covering vast spaces, etc. - the C4 grasses, are all in the 5m-15M years ago period. Imagine an earth with no sprawling grasses.

The problem is the bullshit asymmetry and engaging in good faith.

AI users aren’t investing actual work and can generate reams if bullshit that puts three burden on others to untangle. And they also aren’t engaging in good faith.

Some of this has massively fallen away over the last thirty years. I spent a lot of time on Japanese linguistics, and the really formal tense usage was already falling away even in business context by the mid-1990s. I still find it fun to construct sentences that are practically gramnatical self-abasement but it's not common in actual spoken or written Japanese.

foobiekr··on Psilocybin decreases depression and anxiety in cancer patients (2016)
You've studied it for ten years and didn't notice that the pig brain receptor changes were only measured at +7 days and are replying to a comment about long term effectiveness vs. prozac (which takes weeks to really show impact)?

I have previously read that study. You should put it in context: for example, how quickly does the brain add A1 and A2 receptors for caffeine? (I already know the answer, but you might want to use it to contextualize that study).

The study about the woman co-administering venlafaxine (Effexor) which is an SNRI might be worth considering as non-representative.

Worsening suicidal ideation .. is not unique to _any_ antidepressant. Are you trying to suggest that this is somehow unique to psilocin? We were discussing prozac which is _well known to have this problem_. They got black box warnings for this reason.

As for the heart study, I mentioned this myself elsewhere, and SSRIs are showing the same issue: https://columbiasurgery.org/news/columbia-surgery-researcher... - much worse, however, because people take these drugs every day for decades.

You think depression knows about cancer?

I will up front say that while I advocate taking mushrooms to depressed people, and said so elsewhere, I would not recommend them to _young people_.

But I think you might be missing the forest for the trees: unlike mushrooms, there is a _ton_ of research on pot specifically that illustrates that heavy use in the young is extremely detrimental to their mental health, especially young men. The studies on psilocybin/psilocin do not show this.

That said, Michael Pollan has a quote in one of his books that foes along these lines: coming to psychedelics in old age, when you are set in your ways and everything is locked in, helps you break out and reconsider things, but young people don't have those things, so the value is mostly absent.

Taking mushrooms together with someone you love, who loves you, is possibly one of the most life changing experiences a couple can have.

Have you taken them with her?

foobiekr··on Psilocybin decreases depression and anxiety in cancer patients (2016)
I think this is naive. A mushroom trip is fully metabolized and cleared in approximately 6-12 hours. Despite the similar levels of reduction in depressive symptoms for the subsequent weeks, the psilocin has been cleared on the day of, unlike prozac, and hasn't been stimulating 5HT2* at all for that afterglow and post-exposure period.

Nobody other than crazy micro-dosers is taking mushrooms often enough to cause a change in receptor density and those people are putting themselves at risk of valvopathy due to 5HT2a restructuring of the heart valves (which, as an aside, is turning out to be a problem for people on prozac and other long-term SSRIs).

A drug that is very occasional, point use, with no ongoing use, which has long term treatment results, is absolutely, utterly unlike prozac.

That aside, let's say for the sake of argument that the mechanism is similar for prozac; I think that's wrong (one additional explanation may actually be: https://www.sciencedirect.com/science/article/abs/pii/S15675... ) but whatever. If so, then psilocin is vastly superior to prozac because you are not required to have continuous exposure for the benefits, as the corresponding cost, withdrawal, sexual dysfunction, weight gain, heart issues, etc. are removed.

For other readers, I would like to suggest no music, just a sunny day and quiet.

Music, television, people talking, etc. gives you an external clock and the timelessness of the experience, one of the greatest feelings, is lost.

I guess if you're just doing them for fun it's ok.

HPPD and .. honestly, some people have bad trips, and while it is popular in psychedelic circles to say "There is no such thing as a bad trip just the way you interpret it" that isn't really true. Even Terrence McKenna stopped taking mushrooms for a decade after a bad experience.

That said, I _do_ recommend mushrooms to everyone I know with depression or anger issues.

foobiekr··on Psilocybin decreases depression and anxiety in cancer patients (2016)
I agree with you, but ..

Through direct experience, I do not think 2 or 3 good sessions and you're done is really true. Maybe with experience even that goes - you learned what you needed to learn and there's nothing more to it.

But IMHO psilocin is a strong anti-inflammatory which may in and of itself be some (not all) of the mechanism for alleviating depression (the link between inflammation and depression is strong). That will almost never be lasting.

So we may be in the case where the real breakthroughs are, as you say, in the first two or three sessions. I think most people who took mushrooms out of desperation would agree with that - by the end of the third session many of the things they needed to accept are, in fact, front of mind for awhile. But ongoing maintenance is probably useful.

foobiekr··on Ex-Waymo engineers launch Bedrock Robotics to automate construction
Waymo didn’t do it for anyone else’s gear. They own it all. The liability is all on Waymo.

Traffic laws are a hell of a lot more lax than the situation around on the job injuries.

It is not. These companies are actively hostile to this sort of thing and with good reason: muddy liability in a context where people can be injured, maimed, crippled and killed.

The “add on” thing belongs in he list of tarpit ideas. Watching Cruise and Ghost Automation flail about for years vaporizing cash trapped on this idea was like watching a comedy.

Venture hasn’t managed to make a dent in Nvidia despite massive investments.

Maybe they aren’t as powerful as you think outside the comparatively trivial “build some software” markets. Hell even in networking, compute and storage there are only three or four real success stories in the last two and a half _decades_.
