Gmail and Docs are children's toys for people, who don't know much about e-mail and proper documents. Those are the majority of people on the Internet these days though, so Gmail and Docs are going nowhere any time soon.
If by that you are talking about anything that doesn't have built-in version control and simultaneous editing, good riddance to it and the v4-edited-copy-FINAL-edited it rode in on. But there are a few actual competitors to Google Docs that have built-in versioning and simultaneous editing.
People complain so much and don't appreciate what they have.
Plus, I am supporting content creators better while avoiding ads.
I watch a great deal of YouTube, probably more than any other streaming service now. It's very usable with Premium.
Hard to agree on this one.
Most of the time when I’m the country side of Hungary and some Nordic countries Google Translator it’s essential for communication of foreigners that lives I those places. I can tell several anecdotes of international people being able to communicate with their local in-laws via Google Translator conversational feature; or even cases of people being able to read after a mechanical translation.
Some of the services you mentioned are already very irrelevant:
* Fitbit -- no explanation necessary
* Google translate -- I don't know about if people use their APIs, but for me personally, I have not used translate for a few years. ChatGPT has been my go-to.
* Google Pay -- it has a smaller market share than Samsung Pay.
Then next tiers of services -- they are doing ok but there are plenty of competitors in the field:
* Gmail, Drive, Docs, Groups, Forms, Cloud, Flights, Fi
I even use some of them, but I really don't care if they go away.
Life gets a bit more difficult if Maps, Chrome and Android are gone all of a sudden. Maybe we'll be back to using Garmin. Heck, I love the idea that everybody uses Nokia, Bing or Garmin for navigation, and we actually have a decent website -- like the Yelp or Zagar in the old days -- for restaurant reviews. I still see "#1 Rated Zagat" stickers from near two decades ago at many restaurants.
Anyway, personally, for the vast majority of the things listed here, I don't see them going away being a bad thing that would even affect as many people as you think.
