I'm perfectly aware of the meaning of half-life and of how doping works in semiconductors, but how these topics relate to 'harshness as well as burn in' is totally beyond me!
For your attempts to educate me, I award you 1 out of 10!
There are three options for supporting snake oil:
1. invent quack science but using proper science words
2. talk about irrelevant genuine science and hope nobody notices
3. talk about relevant genuine science and hope nobody does an order-of-magnitude estimate to show that the claimed effect is so far below noise level that even a gravity wave detector would not see it
For some reason snake oil merchants and their fans seem unable or unwilling to adopt the best policy: silence. It is difficult to refute silence, as there is nothing to argue against.

oh, I dunno, as an owner of some of the early PS audio gear - could they be considered "pre-historic" according to the Wikipedia timeline
? *PS Audio - Wikipedia- my interest was piqued when I saw Paul's name, and was particularly moved to chuckle at "gee, don't these glossy magazines smell wonderful?(sic)"
*none of my several PS pre-amps ever blew up, but the original Model One amp on the other hand - well I can just recall that mixing a bridged pair with Polk Audio Cobra cables and Acoustats was not a recipe for sustainability - fortunately, the local dealer had very liberal warranty / trade in policies for repeat kool-aid enthusiasts - which must have been built into the profit margin somewhere.
It is only sensible to look for an explanation if you first make sure that there IS something to explain.

In 1980 I worked for a company who sold Prestel adaptors.
After they were made they were left to "soak" or "burn in" for days.
After that time they would be tested and aligned again.
We found after burn in some had failed or had drifted.
I suspect most of the problems came from overheating rather than anything burning in.
i just bought some hd650 (massdrop hd6xx), and oh, boy did the sound changed from when i first got them (i even thought they might be broken). i ran them with bass heavy music for dozens of hours and took a listen once in a while. Not scientific, but the probes that are my ears and my computer that is my brain (in a way) detected a difference.
i'd guess suspension is getting more supple with usage.
As for electronics...i'm clueless, except that devices are usually encapsulated in a material that influence and responds to the electrical propreties of the diodes,caps,wires,etc...? But i'm more skeptical about that one (haven't ever heard anything noticeable)....

Break-in for mechanical devices, e.g. speaker drivers may show some change after being in use for a while, so some break-in period might be needed. But wires? Nope.

Some electronic components don't burn in either like transistors.
They are just a none changing crystal lattice.
I cant imagine resistors changing much.
Electrolytic capacitors do deteriorate over time.
Other capacitors I suspect not.
Inductors/transformers are stable unless cooked or over current.
