It is sad in states with poor public health the condition you see people’s teeth. There’s always those that can afford dental care. Poor people can practice good habits but being able to see a dentist for a regular checkup/cleaning gives chance to be pestered to brush well, floss, etc. Utah teeth will look on average worse in the following decade
I’d say try Linux. Ubuntu or Fedora and you’ll realize how much of your computer usage is based out a web browser and it doesn’t matter whether you have a Linux, Mac, or Windows computer
Email you’ll be stuck with some corporate entity that won’t be 100% open source. Running an email server and your emails not being filtered is a pain. I use Proton applications for email, VPN, and Dropbox type service. They have a calendar but hard to beat google calendar
Signal for pretty much texting. I actually have around a dozen people I primarily message through Signal so it’s viable for me
Matrix/Element for something like discord.
Onlyoffice, Libreoffice, or WPS Office instead of MS Office. WPS may not be open source
Browser use Firefox or Firefox forks
Krita, Darktable, GIMP for image editing
KeepassXC for my desktop password manager and whatever is available on Android
Maps you can use Organic Maps
Video editing i use kdenlive
People should get it in their mind to never buy Tesla vehicles for the rest of their lives
