Tuning is such a complex and fascinating subject yet many students of music can go many years without thinking too much about it.
I'd say there are many professional musicians who haven't thought too much about it.
There is no right tuning system for music. This is hard for many people to hear including myself a few years ago.
There is no perfect tuning system and each one has its advantages and disadvantages. There isn't even a best tuning system for each situation.
Some would suggest with ample evidence that equal temperament is the best tuning system for Western music such as Bach's Well-Tempered Clavier. Yet Well-Tempered Clavier was written for well temperament, not equal temperament.
In this example well temperament provides moments of glorious, locked-in 4th and 5th but also mandates quite out-of-tune intervals in other spots (which are pointed out in some videos).
In Well-Tempered Clavier, an equal temperament would fix these extremely out of tune intervals at the cost of the rest of the music being more out of tune. You would never find the glorious, locked-in sounds of well temperament when using equal temperament.
One tuning system has advantages while another has others. Neither is better. It comes down to preference.
One might imagine that these problems could be solved with electronic music. Each chord could be perfectly tuned in perhaps non-live setting. This, Interesting, does not fix some fundamental problems.
Yes, this situation could fix some problems with tuning such as a pianist playing the same pitches as the string section playing open strings.
If the string section has tuned using a typical just intonation, then the bottom G string will be most different the piano's G3. This could be fixed digitally either in the strings or piano.
However a huge problem arises when taking lines and phrasing into consideration. What if the violins had just played a solo open G right before. The sudden adjustment to pitch would be noticable to even non-musicians.
Some might say, "fix the piano then". But what if the piano had just been playing a descending G major scale. That sudden drop in the anticipated G would also be jarring.
There is no perfect tuning system and no best tuning system for many situations. This is just a fact that any serious musician has to accept.
Equal temperament has been widely accepted due to its versatility yet its limitations are why we will always see discussions about it.
Tuning along with many aspects of composition and performance is a subject that continues to evolve and evoke controversy.
