Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
This is how NFTs make me feel: like the future is useless but expensive, and world-altering technology is now in the hands of a culture so aesthetically and spiritually impoverished that it should maybe go back to telling stories around the cooking fire for a while, just to remember how to mean something.
There is something about the aesthetics of NFTs — not a sameness, exactly, but a particular deficiency of which they all partake, such that even though they look different, they all manage to suck in the same way. It’s tempting to say they suck the way everything sucks now, but it’s more like how one particular strain of American aesthetics has sucked for the last 20 years. NFTs are the human capacity for visual expression as understood by the guy at the vape store.
