How many times can you bend the cable before something gives? Not many, and this was a $3000+ cable that was sent to me for retermination. A couple years or so after it was reterminated it developed an internal short somewhere. Then there's the air/cotton dielectric folks, hate to break it to them but copper and/or silver corrode over time, and while an air/cotton dielectric sounds very slightly better vs teflon the wires do corrode over time. I've been making cables for over 20 years and I have plenty of proof of this as I went through a period of making cables with wire in teflon or cotton tubing. Now I use cotton as a cover that damps mechanical vibration without degrading the sound, the wires under the cotton jacket are teflon insulated.
    Corrosion is definitely an issue. This is why I hermetically sealed my interconnects and put silver oxidation inhibitor in there. It's a more serious problem for copper. Copper is fine, as long as its silver-plated or tin-plated. Stranded copper is the worst IMO. Never touch the stuff.

    Not a valid concern IMO. This happens within 1" of the cable. Fields fall off exponentially. People have this concept that fields are being picked-up by everything. Simply not the case. RF fields can be picked up by loop antennas, like ground loops however.

    I used to own an auto/welding shop and have seen plenty of corroded wires in autos, all stranded copper, the corrosion starts at an end and works it's way down the wire. Some say corrosion doesn't matter when talking about audio cables but I've seen many wires simply stop working and not just battery wires... power window/door wires, fuel pump wires, all sorts of wires just stop working after a while when they corrode.

    I did build one cable with wire in teflon tube, then flushed the tube with nitrogen gas and sealed the ends. It is slightly better vs teflon insulation that conforms to the wire, but labor is a PITA and the ends of teflon tube require some not-generally-available adhesives to properly seal.

    It depends on type of copper and the insulator. I had some Mogami cable (4mm2 multistrand with ultra thin wires) about forty years old in storage in my garage and recently looked for it and stripped the insulator at the extremes to fit connectors - it was like fresh copper wire, no vestiges at all of oxidation.

    I got some stranded copper wire once from a surplus electronics place. The stuff was so awful, I don't think you could light a lamp with it....

    My interconnect cables were bare silver, supported by a custom structure that I fabricated. A bit better performance, and more durable than sewing through a cotton rope. I think a number of cable companies are doing this now.

    It does not take much, less than you can see. The more pure the copper is, the slower it will oxidize, so that was probably the reason.
