Anecdotal evidence, not backed up by data. Actual data clearly shows that Google is the leading search engine across all age groups.

These aren't incompatible issues. Google has a monopoly maintained by excessive and illegal anti-competitive practices. The majority of users have no clue how to even change their default search engine, which Google actively exploits. Just checking it out - it took no less than 6 clicks into various specific menu and sub-menu settings to do so.

Poll only the subset of people that are actively aware of how to change their search engine and I suspect Google's dominance suddenly completely disappears. Remember, there was a time when Internet Explorer was the leading web browser across all age groups. Then Microsoft was forced to make it easier for people to change their default browser, and suddenly nobody was using IE anymore.

My apologies, I did not mean to imply that my kid's humour is evidence of Google's demise. But it does make you wonder a bit... we use Google out habit (they used to be decent) and also because they pay boatload of money to be default search on iphone and myriad of other reasons but younger generations do not have that intimate relationship with google and can see "with fresh eyes" its usefulness compared to the alternatives ...
