I believe you, but it was just humorous. You referred to 'available bandwidth' being greater, and

Greg talked about a 'wider path'. Well, to a rank amateur like me, 'greater bandwidth' and 'wider

path' sound pretty similar!

There are basically two ways to achieve greater bandwidth. One is to

send data at higher speed in a single stream. That works but it is

presently running up against the speed of light, as well as density

and cooling issues. The second way is to break up the data into

multiple parallel streams, i.e., "a wider path", sort of like

converting a two lane road into a 3 or 4 lane road so it can handle

more cars.

Early in my career, I laid out PC boards. Did it on a light table with tape, pre-cut pads and an Exacto knife. A lot was audio, with some microproccessor and logic control. I'm glad I moved on before things got so fast that you had to worry about electrons running off the end of right angle copper trace runs. The audio was interesting... lots of games played to reduce crosstalk between paths and to improve S/N. That was fun.
