So is science essentially over? The author certainly seems to think so.
Could we then postulate that a similar thing has happened to music through the years? Whilst it would take some time to go through all the styles (and bearing in mind that a lot of styles are not overly concerned with breaking new ground) if we broke it down to four main contenders - orchestral, jazz, rock and electronic - I get the feeling that there is little new ground to break that hasn't already been broken.
Which brings us to the most recent of the four. Kraftwerk led to Afrika Bambata and hip hop and electro, which had inspired the emergence of techno and house by the mid 80s and within a few years we had trance and hard house on one side and the re-emergence of sped-up breakbeats in hardcore and then jungle by the early 90s. Techno and house were re-invigorated by minimalism and glitch via Basic Channel et al, hip hop led by J Dilla returned to unquantized beats (a precursor to such "fresh" sounds as "wonky") and incorporating more tech sounds thanks toTimbaland, jungle mutated into the no-holds-barred invention of drum and bass and then a combination of heavily swung beats, booming bass and a return to divas and mc's led to UK garage and 2 step.
After that, it seemed that pretty much all electronic dance music pretty much regurgitated itself - grime took the mc and gun culture from hip hop, lost the funk and gave it a darker, harder spin (not unlike the trajectory of post-99 drum and bass); dubstep took the jungle bass, techno minimalism, quacking dnb basslines and somehow turned raves into monotonous, metal gigs; bassline ripped speed garage in a hard house style and electrohouse seemed to just rewrite the same song forever. The non-dancey stuff isn't much better - has anything particularly new happened in noise, ambient or drone in....oooh... the last 20 years or so? The aha! moments that triggered the accelerated evolution of this period were created from a combination of new technologies (e.g. drum machines, synths and samplers) and frenzied experimentation with them (e.g. "impossible" drum parts, cut-up breaks, resampling). Now that we can distort, pitch-shift, timestretch, flip, reverse, rinse and repeat have we not got to the point where essentially it's all been done?
It seems to me that music in its current state can only provide diminishing returns given the amount of music available and the history involved. How many more combinations of notes can there possibly be that have not been used endlessly before? How much of what we considered imagination were lucky mistakes with technology or using it in ways that had not been tried before? What is the limit to imagination - isn't everything we imagine something that is already in our mind or a combination of sounds we already know?
Are there going to be any further innovations in technology that might allow us to create unheard sounds? It seems again that most of the major discoveries are done if we can manipulate audio at the sample level - we can now even improve on a virtuoso performance. Once we have covered the extremes, is there anywhere else to go but creating hybrids and filling in the few gaps left?
Is this the end of music?
