Both software and physical engineering can hide junk. It just depends on who is looking. There are plenty of products made that are junk. If you start to understand how products actually come to fruition in the business world, you will see that most of what we buy or sell or see marketed is actually junk. This is because engineering both in software and in the physical world is rarely, if ever, incentivized to seek out a perfectly optimal solution. What is able to generate profit sufficiently over costs, today with today's economic context, is what ends up getting shipped in both cases. That might change tomorrow and suddenly the product is not viable due to the costs of the junk associated with it. We talk about legacy code and how it is junk we are beholden to, go ahead and look at the engineering behind car designs and you will see there are legacy engines, legacy car platforms that people are similarly beholden to no different than legacy code people are afraid to touch. And that is just that one sector. Legacy engineering is present in everything you can conceive of due to the fact no one is paid to go off into the woods and optimize optimize optimize, only to ship by a deadline even if it a stinking pile of you know what. That is for sales to figure out.
