Do people often thumb letters instead of swiping? And why? Coding or other stuff where you don't have natural language?

For her swiping (or glide typing) is the only thing making mobile phones somewhat usable, but I also encounter people who haven't even heard of that feature.

I usually just type with two thumbs and can type pretty quickly. Swiping always felt a bit awkward to me because my phone is too large to use one handed with one thumb swiping, and swiping with a finger felt awkward compared to just holding my phone in both hands and typing with both thumbs.

I imagine if you look at how most young people use their phone, it will mostly be the two thumb method and they will likely be very quick with it.
