Ah sorry my comment is ambiguous; I’m saying I 100% prefer butterfly keys over the new 16 inch keyboard. I’m sure I’ll get used to it though.
Gotcha. I do like typing on the butterfly keyboard. It's just problematic that keys will randomly not respond or send multiple strokes, and can't be fixed short of taking the entire computer apart.

> it seems pretty likely that I will be protected And you'd be wrong. Sure, a face shield will protect you from liquid streaming out at you (partially). However, it isn't a liquid that you need to protect yourself from in this instance... it is aerosolized particles. And those travel in the air. So when you breathe in, that air can and will move around the face shield. The sibling comment about smoke moving is exactl…
You say that with great confidence and a lack of sources; and I'm guessing we are equally ignorant on the actual physics of how small droplets move. The details aren't clear on how the virus is spreading. The virus might have multiple modes of transmission. Closing 2 of them reliably a great deal. There are important things to do with "catching COVID" that aren't binary; starting doses likely matter as well. I'd rath…

I'd be more concerned about Chinese suppliers who have privately said they would supply faulty equipment related to corona virus to the US.
Really? I would consider unchallenged, systemic slavery to be a fairly important problem. Not something to be dismissed as less concerning than another critical issue. I am just surprised by the complete lack of news. How many people do we think would choose not to buy a smartphone made in China this year, if they knew the supply chain used slavery. Sadly, I don't think people care - as long as they get the latest iP…

> I was hoping everyone in the US might be able to buy one. This burst of PPE being produced in mass quantities are and were never meant to go in the hands of the general public (i.e., non healthcare workers), though. The general public does not need to be walking around with a full face shield, that’ll be a waste of materials, time and money, unfortunately.
Given that they probably would cost $1 to $5, and take almost no space to store, it wouldn't be a terrible thing for people to have a few if they want them. How many people have a $20 multi-tool that stays in a drawer somewhere? Or some bags of rice "just in case" that end up getting thrown in the trash after being forgotten about in the cabinet for 5 years? It may not be a terrible thing if some percentage of people…
You need to not only know how to use PPE, but know what it's limitations are, and what it's designed to actually protect you from.
Wearing a shield thinking it provides any protection from an aerosolized virus is a perfect example of having the wrong expectations from a piece of equipment.

Because humor is "negativity". Maybe don't make people feel worse. Thank you.
“Tragedy plus time” is the standard formula in that vein of humor. Let’s give the victims time to succumb and their families time to grieve before breaking out the glib cynicism toward other peoples’ lifesaving actions.

It's not about the money. PPE like face shields are specifically used during procedures that involve significant bodily fluid, like intubation, which is the process of pulling or pushing a tube down a patient's esophagus. Going to to the grocery store does not require a shield. Secondly disposable medical equipment, when used properly within a healthcare environment, is extremely wasteful. For most consumable items u…
Pedantic point: If you’re intubation the esophagus, you’re doing it wrong. :-)

"Everybody stocking a "handful" of PPE isn't a scalable solution to maintain a national supply." No, but there's no harm in it either, and some potential benefit in case it takes a few days for the federal government to organize a response. We all assume the government is going to make sure the food supply is maintained, but everyone is also buying some extra food just in case there's a temporary gap. We don't need t…
"We all assume the government is going to make sure the food supply is maintained" Do you assume this? I assume that capitalism is keeping the food supply maintained. When that fails, I think we're up the creek.

If someone is facing me and a stream of airborne particles hits a plastic shield instead of streaming out to me, it seems pretty likely that I will be protected. I'm certainly open to the idea that fluid mechanics are complicated and somehow air currents are going to do unhelpful things, but until I find someone with a paper on the topic I'd much rather be talking to someone wearing a face shield than not. Plus obvio…

The 3D model absolutely can scale.
Sure. But for an equal amount of effort, raws and manpower you could get much more out of traditional manufacturing, much quicker. The product is a very simple stamp, with very simple dies with little wasted material. Perfect for traditional production methods. It's great people with machines are contributing to the effort, and empowering/informing individuals to be able to do so as well. But it's just done simpler t…
The set of people who have 3D Printers at home, and the set of people with access to large-scale injection-moulding facilities (along with tool production) likely have a very small overlap.
I imagine those that do have access to those facilities were already trying to make those tools (assuming they wern't already occupied with other more urgent tasks). It just takes longer for them to scale up, and there's fewer of them in a smaller number of locations.
