Do you all remember barrel plugs on laptops. They would often degrade. Either the cable side or the device side of the connection or both. That was the most annoying part of barrel plugs. They would last 8 years and then stop working consistently.

In theory if you are going to design something new, you are going to take the most annoying part of the past technology and solve that problem. If the existing technology is perfect in every way except that one area, it would be silly to solve other problems.

We've had a couple generations of plug solutions come about since then, and we still have the same problem. And the timeline of these thing is shorter than the 8 years it took to degrade a barrel plug.

So why haven't we solved this?
