Increasingly, yes. It's shaping to be (ironically) the sugar of the 21st century, where sugar was touted as healthy in the 50s despite the effects on diabetes and obesity that we're still seeing now.
In regards to focus and typing speed, laptops seem to do it best for me. My laptop is usually in sleep, and my desktop off, so it's much faster to bring it from sleep and do what I need to do. A laptop, too, was my first computer, so I feel fairly comfortable with the experience unless I really need a mouse. Desktops are insanely comfortable, though, and I guess primarily that's what I'd use, but thankfully I can do about equal things on both outside of gaming, so it's mainly about how I'm feeling at the time.

Thank you for reminding me of Librewolf, I haven't brought myself to install it yet. I wanted to move my profile over, too, though I'm unsure how seamless that would be (it's worked with other forks I've tried, so maybe it's easy).
Thankfully, I've been about Firefox since 2006. People can use what they like, but it does ache me inside seeing someone use Chrome, logged in with the yellow "Update" icon at the top right, an unholy trinity.
There's something that a person close to me said about certain tech/features that stuck with me and seems to click here, it was: "A lot of it just stops you from using your brain."
