I don't really understand this comment. Surely to write well-written code you need to understand how computers work. Just like understanding how cars work is important to be competent at servicing and repairing cars.

Saying "it's an unfortunate fact of life that programming is tied to computers" is as weird as saying "it's unfortunate that being a car mechanic is tied to cars". The job exists because of computers and cars - not in spite of it.

If you wanted a problem solving or engineering job that wasn't tied to computers then there are other options, like a mechanic, electrical engineer, mathmatition or working in any of the numerous fields of science. But a the end of the day, you're still going to need to understand the core principles of that field if you want to be effective in it.
