I kinda had this sentiment until I actually started working - quite often an issue only manifests at an obscure customer system or is a race condition that it too rare to catch reliably, yet happens often enough so you can't just ignore it.

To solve those in a reasonable amount of time, you need to form a mental model of what is going on & how to fix it. Having access to a computer by itself won't really help for those.

In that context paper exams for computer science make much more sense to me now - they want you to understand the problem and provide a solution, with pen and paper being the output format.
