> Hoy said that long before stonecutters started struggling to breathe, the sheer amount of silica in many kinds of engineered stone — upwards of 90% — should have made it obvious that the material was risky to cut and grind, especially in workplaces without sophisticated measures to control dust.(1)

> But scientists and regulators have grown concerned about whether recommended strategies such as wet cutting, proper ventilation and wearing respirator masks can do enough to protect workers from dust so high in silica. Cal/OSHA officials have generally described silicosis as preventable, but also caution that with 93% silica(2) content, “safe use of engineered stone may not be possible” even with proper workplace practices.(1)

How about instead, mandating that all IoT devices need to comply with an open standard? Customers would be free to connect their device to Siri or Alexa if they wanted, but by default the device just works with an open standard that you can control fully, hosted at home if desired.

It would also remove the cloud security onus from the manufacturer—they would fund the standards org, which would be responsible for the security of the interface.

We already have this concept for electricity, phones, networking. You don’t buy a “MA Bell” phone anymore or an “Edison-compatible” fan.

But the most important issue is that as long as malware can spread through ads (https://en.m.wikipedia.org/wiki/Malvertising), everyone should be blocking all ads.

- the current plans for Breakthrough Starshot[0] are to send a centimeter-sized, ~1 gram mass spacecraft.

- even such a tiny spacecraft would require a 4x4-meter solar sail and 100 GW of laser power, because photons carry such small amounts of momentum

- a ground based nuclear power plant produces a couple GW of power. 100 GW of continuous laser power would require the entire output of 50+ nuclear power plants

- that amount of power is difficult enough on the ground, trying to put 50+ nuclear power plants worth of energy generation on a space craft would alone be a tremendous challenge

- assuming we could do that, it would weigh unfathomably more than a gram. Just the fuel alone in a ground based station is several tons; the infrastructure to turn that fuel into power is many thousands of tons more… times 50+. It would not be impossible for that amount of power generation to weigh a megaton.

- assuming it could be launched from earth or built in space, and pushed by solar sail, the solar sail needed for a ship weighing a megaton would be another level of challenge. If 16 square meters of sail are needed for every gram, then a megaton would require 16x10^12 square meters. That would be a manufactured object 4,000km on a side, or roughly the size of Russia.

- We haven’t accounted for the increased power needed to power this craft by sail from the ground. Momentum (let’s ignore relativity even though we are talking about reaching speeds where that starts to be important) is mass*velocity, so in order for our megaton-class spacecraft to be pushed with the same performance as a 1 gram spacecraft, we’d need to scale the momentum delivered by photons with the mass of the craft. That would require 10^12 (one trillion) times more laser photons, which would require one trillion times more energy to produce and 50+ trillion ground-based nuclear power plants.

- I think it’s safe to say that pushing a megaton-class starship with lasers and a solar sail is unfeasible. But wait, if we’ve managed to assemble and launch the craft, we don’t need the ground based lasers or the sail, we can just power the ship using all those power plants on board. [1]

- with a ship that large, we could take a city worth of people along for the ride, so is there still a use for the giant laser we’ve brought with us? Maybe interstellar package delivery?
