You don't need long passwords, just reasonably good ones, to defeat online guessing. Estimates of how quickly billions of guesses can be performed assume that all your encrypted passwords have been downloaded and can be subjected to brute force, offline. That means your security has already been compromised.

Apparently, you don't fully understand the difference between physics and engineering. Technological barriers can often be overcome with advances in materials and design. Declaring them to be insurmountable has been shown to be foolish, many times. Barriers imposed by the properties of matter, on the other hand, are much more durable. Declaring them to be insurmountable is rarely a mistake.

The FAA doesn't use the term "drone" for anything. This thing, tethered or not, is a model aircraft. As long as it is used for hobby purposes within the guidelines for model aircraft, the FAA doesn't care. What the FAA does not allow is any unlicensed aircraft (which includes models, balloons, kites, gliders, rockets and probably tennis balls), tethered or not, to be used directly or indirectly for commercial purposes.

At Texas Instruments, an integrated circuit was called a "bar", not "chip" or "die", partly because that's what Jack called them. Wafers were called "slices", so your multiprobe yield was expressed in "good bars per slice". They finally dropped the Texas jargon in the mid-'80s when it became obvious that it was a silly affectation in the face of industry-standard terminology and an obstacle to communicating clearly with vendors and customers.
