I think if you were to ask "most people" about which search engine they prefer, they wouldn't really understand the question. I remember in highschool a teacher asked someone what operating system they have at home, and she replied "I think it's Microsoft Office".

Tech people tend to severely overestimate non-tech peoples' understanding of tech.

I made a list of the Google services I needed to replace, replaced a couple of them, but ultimately that list had dozens of items on it and I'm too tired already to complete it

It is not easy. This comment must be satire?

For example have you tried navigating in a car with a navigation app besides Maps? I don't have an iPhone and the ones I've tried so far suck. I mean, I think Waze isn't even all that good and Google owns even them now.

While I don't believe you can degoogle that quickly, because some of their services take quite some time to properly switch, such as email, in the end it's not too hard, but just takes time and some work.

Changing email is easy, if you don't mind it being a slow process. Just forward your google email, and start slowly replacing any service you notice in the following months/years to your new address.

Google Drive is harder to replace, I went for just running a NAS with Nextcloud, which takes care of most of Google Drive/Docs/Calendar stuff. If self-hosting isn't your cup of tea, Proton is slowly setting up usable google alternatives - they have Drive and Calendar IIRC.

Now for phone, that's the hardest task. You wouldn't help yourself by getting an IPhone. While it would de-google you, there's basically no point in switching google for apple. Getting android to be usable for stuff like banking, MFA and other bullshit you need your phone for while being degoogled is hard, due to the bullshit Google Services. The only solution I found is to either just go with dumb phone with an obscure OS, or just get a Google Pixel and run GrapheneOS.

Maps are another issue, but thankfully we have a local https://mapy.cz/ , which is a pretty OK alternative to Google maps for our country, and I guess they even work worldwide. I don't drive a car, so I don't really need it that often.

The only remaining Google service I use is GCloud VPS, because I have some websites running there on the free instances that I'm too lazy to move. But I'm slowly migrating it to Amazon. Not that it would help much, anyway. And also Youtube, but I'm trying to go through the alternative front-ends as much as possible.

And for browser, I'm using https://mullvad.net/en/browser. Fuck chromium.

Migrating email alone is a huge pain. To be truly independent you need your own domain in case whatever provider you choose goes to shit. Any decent one will cost money. Now, most people don't even know what a domain is, let alone where and how to buy it and use it for email. They also have to pay that mail provider, configure everything and migrate their old emails and forward their old mail. Oh and now they also have different logins everywhere, and because they probably don't have a password manager either they need to get one or just have different logins for different things.

That's ... a gargantuan task. for an average person - even if you provide them with a rough outline of what they'd need to do they probably wouldn't be able to do so without help.

Also, as a side note, what do you use for watching videos? What phone do you have? What maps do you use? It's not so easy to "de-google" completely.
