There are pianos, violins and guitars made today with carbon fibre tops and soundboards. They are more efficient resonators, so these instruments are usually more responsive and effectively louder than those employing spruce (or pine, cedar etc). But musicians playing traditional instruments are a conservative lot (understandably so, habit being at the core of instrumental skill), and most seem to favour the 'warm' character of a plank of wood over the high-tech appearance of woven carbon.

Thank you for that, good sir. What an eloquent illustration of proper thought.

"If the physical universe ceased to exist, would the rules of chess remain the same?"

The answer is "yes". Because the rules are metaphysical, not physical.

The answer is "no". Because there is nothing left, there is no record of any rules left, therefore there are no rules.

Your "solution" to the question postulates that something is there which will keep a record of the rules. A mistake common with people who have yet to come to fully accept their own mortality.

QuickPar on Windows is long-obsolete. MultiPar is the more modern variant.

Has there ever been a backdoor in Windows or other Microsoft products? No.

Yes, there have indeed been numerous opportunities to get complete access to Windows systems from outside. It appears that you simply prefer not to call them backdoors -- perhaps "vulnerabilites" is the first word to come to your mind. The difference is intent, and that is impossible to judge.
