Relatively, this is just in the past week - alone!
In that week there is ---much, much much more.
It is moving so fast right now that even a child born today in the best environment possible, which is created by outdated people...might be woefully outdated by the time they are 10 years old. It’s an overt statement, on my part - but difficult to truly disprove.
And to remain inflammatory as, after all.. this is an audio forum...those physics news links, specifically the ’electron behaviour’ one will ~flat out tell you~ (in matter of fact terms) that what is going on in the liquid metal cables is beyond everything you know in physics. Whoops.
So no, it’s not business as usual and snake oil. Not scientifically possible to be 'hooey'. It's a totally different animal than wire. Big time.
