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.

In the past, the manufacturing processes for analog and digital circuits were so different that they could not be combined on the same chip on a large scale. There were big companies that made digital chips and a host of smaller companies that made analog chips. That changed about ten years ago and analog circuits are now included on SOC designs. That has caused a shift in the industry, as the large SOC manufacturers have absorbed most of the new analog circuit designers who used to go to smaller companies that specialized in analog. The smaller companies are faced with competition for designers and a shrinking niche for their specialized products.

Texas Instruments has $12B in sales and analog is a large (and growing) chunk of that.

Some people carve careers, others chisel them.
