One of the casualties of modern media is patience and concentration. Professional web developers are trained that a website which requires the user to search for more than 4 seconds will result in the user clicking the back button and finding another website.
However, when you look at all of the major intellectual accomplishments since the middle ages, they have all been due to the ability to study and concentrate (something developed, for Westerners at least, in the monasteries and later in the universities) and focus carefully on minutia. No one can comprehend (much less improve upon) highly technical sciences like quantum mechanics while "multi-tasking".
So far I have seen no evidence that whatever skills that modern youth are developing through multi-media consumption will be more efficient or of greater value than the skills that they are demonstrably losing... including those patterns of thinking that have created the modern world and all of its advances...
The convenience of the web spoils us. That four seconds may whittle down to two as overall performance improves in the future. People get expectations.
