It depends. For new tech startups it's becoming the standard and until your market expands beyond tech I feel like .io is fine.

regardless, it will sound outdated in a few years. its not based on what is currently fashionable.

its not a name you should give your company if you want to last say 10 or 50 years

in germany there are all these companies called 24 like http://www.immobilienscout24.de/ because back in the 90s this was the trendy german website thing. now it just sounds silly

just in case it isn't clear: the 24 means "open 24 hours a day" - which is pretty exciting in a country where supermarkets are closed on sundays
