Keep in mind relative quality means a lot. You can buy a cheap just about anything that will die near the end of itâs lifetime, or you can buy expensive versions that probably wonât break in your lifetime.
Also, a lot of earlier designs were pioneering and required over-engineering, whereas modern stuff has much closer tolerances because they know what things can do, and you pay for how long something is going to last.
Also also, it would be more realistic to look at the actual failure rate as opposed to comparing their durability directly. Most of the surviving stuff from âthe good old daysâ is probably high quality, over engineered, and/or happened to be one that lasted a long time.
