Our "vastly more efficient and productive daily farmers" are given federally subsidized price supports to the point of massive overproduction so that the American consumer has stable milk prices.

Tip of the iceberg (lettuce).

US farmers are provided massive subsidies for agricultural water versus what you might pay in a single family urban household.  Difference is price is somewhere between two and 3 orders of magnitude - no joke.  Remember that next time you're shopping produce.

Not a schematic. Pictorial drawing.

Those illustrations there are not realistic depictions of the device, but a schematic illustration including only information relevant to the purpose (in this case, dimensions for case makers), and nothing more. 

That is the definition of a "schematic". 

Assuming it’s for case makers then it’s an ICD (interface control drawing) with an OML (outer mold line).  So there!  😁

...  I’m talking about ordering ASTI 304 steel, getting something that wouldn’t even pass 201 standards ...

This is the dirty little secret about Chinese steel.  Their specialty steels are not to be trusted.  A few years back the company I worked for at the time wanted to outsource some of their power generator components to a Chinese manufacturer.  We gave the supplier prints and specs from a proven design for a permanent magnet.  When we received the parts and assembled it the permanent magnet would not work, which perplexed everyone, until we tested the metal and found it was not what we asked for and not what they claimed.  We pulled sourcing back a short time thereafter.  Expensive lesson to learn.

Imagine all the hand holding Apple has had to go through over the years to ensure quality in their Asian supply chain.  It must have been a staggering undertaking and a testament to Tim Cook.

Noam Chomsky used to say that some of the most accurate papers are the financial ones, like the WSJ and FT, because the markets *require* accuracy, otherwise business decisions may be based on falsities and the markets can't handle that. Of course that was before Murdoch bought the WSJ, wonder if Chomsky still thinks that today about those papers' (particularly the WSJ) being more accurate than the rest?

Since when did Noam Chomsky understand anything about financial markets or business or capitalism in general?  And what what does Murdoch have to do with any of this?  Wall Street has been seen as a crap shoot since it’s inception, with a mix of rational players, irrational players and criminals masquerading as impartial brokers.

How would the psychics of that work? How good can a 1 inch* tweeter as an entire channel sound?

Acoustic beaming, as Apple calls it, gets into some pretty hairy physics.

For beam forming to work you need to create two or more almost opposite sound waves that rely on constructive and destructive wave interference.  Constructive interference will permit the sound waves to travel.  Destructive interference will act to cancel out the sound wave in the direction it is not desired, a la noise canceling headphones.  That’s actually the easy part.  The hard part is capturing the acoustic properties of a room, figuring out where you want to project each channel, deciding which speakers to use for constructive and destructive waves (and by the way one speaker can project more than one sound wave, so how do you parcel that out in software), and then directing the constructive and destructive wave beams accordingly.

It’s so ambitious that I don’t know if Apple can pull it off.  But I believe this is what Apple’s acoustic engineers would like to do.
