Quick reminder: anything can be turned into a book, anyone can write one. There's no regulating body, authority or even peer pressure overlooking the veracity of what's written.
Your weird uncle can write a self help book based on a random dream he had.
You might have heard a teacher complaining about using Wikipedia as a source... books aren't different, you need a lot of supplemental research to use a book as a source in order to verify it's valid as one.
Acetaminophen
Which is an horrendous drug that's extremely toxic for your liver, easy to overdose on, and only recently known to need a lower dosage for safe usage by women. However, it's the US' go to drug because of a commercial dispute and marketing campaign against metamizole, which may perhaps once in a blue moon if you're very unlucky and maybe perhaps predisposed cause immunological complications.
Acetaminophen is seriously scary to be taken as lightly as it is in certain countries. Do not buy it simply due to a cold or flu.
It's just Tumblr being Tumblr: they knew exactly what they were doing, they knew the philosophical concepts already, but the posts must be phrased as some whimsical discovery mixed with internet humor and spontaneity otherwise they do not get reblogged.
That's always the Tumblr structure and tone. You can't post an explanation or reference or author, you need to make it sound like some shower thought.
Apart from all the other benefits, one underrated feature of SteamOS over Windows for a handheld is how GameScope handles windows:
On Microsoft Windows, if a game from 2008 boots a menu for configuration before the game itself, it's usually this tiny Windows 98 square that you need pinpoint precision to maneuver. Worse still, if a launcher or firewall or whatever decides to pop up a window on top of your fullscreen game, the screen flashes three times, the mouse focus can attach itself to the wrong panel, and it can be super annoying.
On SteamOS, any window will scale to your full screen size - including those ancient ones. There will be no firewall or defender or whatever prompts, but if a game launcher does decide to spawn a new window, focus is not lost and changing between windows using the Steam button is simple, fast and the input will always work on the correct window.
It's the absolute best way to turn PC software into a console experience. Windows solution to this same "how to make a PC feel like a console?" is adding yet another layer on top of everything with the GameBar, then make it inconsistent by changing the UI on gamepads, then make it even more inconsistent by changing your saved layout after every update. The GameBar fixes zero issues.
