What about some successor to neuralink being used to provide a person with a two-way interface to the internet, and have immediate access to essentially all knowledge? Would we outlaw procedures from altering people in this way?

If we do, then those people will just have to move to Mars.

Amazon is one of if not the largest company on earth.

Not by anyone's measure.

If you go by assets or a mix of assets and sales, they're not in the top 20.

If you go by revenue, they're #9.

If you go by employees, they're #4, with less than half as many as Walmart. I guess this metric would make it in to 'one of the largest'.

Because then people will forget about the basic skills! Just like those pernicious books, downplaying the basic skills of memorization:

If men learn this, it will implant forgetfulness in their souls; they will cease to exercise memory because they rely on that which is written, calling things to remembrance no longer from within themselves, but by means of external marks. What you have discovered is a recipe not for memory, but for reminder. And it is no true wisdom that you offer your disciples, but only its semblance, for by telling them of many things without teaching them you will make them seem to know much, while for the most part they know nothing, and as men filled, not with wisdom, but with the conceit of wisdom, they will be a burden to their fellows.

Cops Are Playing Music While Citizens Are Filming To Trigger Copyright Filters (vice.com) 230

An anonymous reader quotes a report from Motherboard: Last Friday, a man entered the Beverly Hills police department, only to be treated to a mini DJ set that could potentially get his Instagram account banned. Sennett Devermont was at the department to file a form to obtain body camera footage from an incident in which he received a ticket he felt was unfair. Devermont also happens to be a well-known LA area activist, who regularly live-streams protests and interactions with the police to his more than 300,000 followers on Instagram. So, he streamed this visit as well -- and that's when things got weird.

In a video posted on his Instagram account, we see a mostly cordial conversation between Devermont and BHPD Sgt. Billy Fair turn a corner when Fair becomes upset that Devermont is live-streaming the interaction, including showing work contact information for another officer. Fair asks how many people are watching, to which Devermont replies, "Enough." Fair then stops answering questions, pulls out his phone, and starts silently swiping around -- and that's when the ska music starts playing. Fair boosts the volume, and continues staring at his phone. For nearly a full minute, Fair is silent, and only starts speaking after we're a good way through Sublime's "Santeria."

Assuming that Fair wasn't just trying to share his love of '90s stoner music with the citizens of Beverly Hills, this seems to be an intentional (if misguided) tactic to use social media companies' copyright protection policies to prevent himself from being filmed. Instagram in particular has been increasingly strict on posting copyrighted material. Any video that contains music, even if it's playing in the background, is potentially subject to removal by Instagram. Most people complain about these rules. Beverly Hills law enforcement, however, seems to be a fan.
"Under most circumstances, civilians are legally permitted to openly film on-duty police officers under the First Amendment," the report notes. "And while the interaction between Devermont and Fair is pretty benign, BHPD's recent behavior suggests that at least some cops believe they can prevent themselves from being filmed or livestreamed by playing copyrighted music, which would have serious implications for more serious incidents of police misconduct."

In a statement emailed to VICE News, Beverly Hills PD said that "the playing of music while accepting a complaint or answering questions is not a procedure that has been recommended by Beverly Hills Police command staff," and that the videos of Fair were "currently under review."

Figure caption:

Left: mass function resulting from a flat power spectrum such that it peaks at 10 14 M , with A 5.8 × 10 3 and k s = 10 9 k l 1.6 Hz , and PBHs comprise the totality of DM, i.e., f PBH = 1 . In the tail of the population, around M , one can notice the bump in the PBH production due to the decrease of the threshold by QCD epoch equation of state [24,51]. Shown are the most stringent constraints in the mass range of phenomenological interest coming from the Hawking evaporation producing extragalactic gamma ray (EG ) [54], e ± observations by Voyager 1 ( V e ± ) [55], positron annihilations in the Galactic Center (GC e + ) [56], gamma-ray observations by INTEGRAL (INT) [57] (for other constraints in this mass range, see also [58–63]), microlensing searches by Subaru HSC [64,65], MACHO-EROS [66,67], Ogle [68], and Icarus [69], and those coming from CMB distortions by spherical or disk accretion (Planck S and Planck D , respectively) [70,71]. LVC stands for the constraint coming from LIGO-Virgo Collaboration measurements [72–74]. We neglect the role of accretion, which has been shown to affect constraints on masses larger than O ( 10 ) M [75,76]. See Ref. [4] for a comprehensive review on constraints on the PBH abundance. Notice that there are no stringent constraints in the PBH mass range of interest [52,53]. Right: the abundance of GWs according to our scenario. In black the 95% C.I. from the NANOGrav 12.5 yr experiment is shown. For more details about the projected sensitivities, see the main text.

The right-side plot is a predicted gravitational wave observability, and the colored ranges are the various existing and (mostly) proposed detectors. The paper's survey is the small black area.

For this particular hypothesis, Hawking radiation is not an issue. It's very difficult to see in the non-PDF image, but the left plot of Figure 1 shows the detection bounds.

The leftmost exclusion area (red) is limits on distribution from Hawking radiation background as measured by extragalactic gamma rays; the rightmost (blue) is CMB background distortions, and the zones at the top are various microlensing surveys. The blue line is the paper's hypothesized mass distribution for 100% dark matter.
