I kind of want to be a CTO somewhere. So much bureaucratic stuff to become one though. You usually have to be someone's friend or start a company yourself.
Same, I am looking forward to starting my own company in the next year or two, and exploring the CTO role, especially after so many years as a Staff+ operating as an arm of CTOs and learning the ropes.
If you enjoy building its kind of a pain in the ass.
I've been the CTO twice in my career, and am in a pure engineering role now and get a lot more satisfaction out of my job.
