A lot of people type without having to look buy without using the proper technique, essentially doing hunt and peck with two or three fingers but with good muscle memory. Proper touch typing is about using specific fingers to specific keys and remaining on the home row when not in use.
Yes, that was me! Two or three fingers per hand. I think a lot of us do like that. I learned the proper way like a year ago. I sill had to force myself to put my fingers on the home row. The problem is I use their laptops in weird places like on a couch or bed where proper touch typing is just not comfortable and it easier to type one handed.
