We build on the shoulders of giants and there's nothing wrong with that. The terminal is just one abstraction down of an abstraction of an abstraction of an abstraction of an abstraction of an abstraction. Not very impressive.
Linux disagrees with you. A process is a core thing to the OS, not just "another abstraction". The terminal is an extremely shallow/direct interface to the OS, in a way distinctly more clear & certain than most other abstractions.
There's no better way to see real truth in computing. The shell exposes the base truths of the OS abstraction directly: processes, environment variables, stdio, signals, pipes. This is the fundamental toolkit of computing, and what higher-level abstractions we see (from language's stdlibs, to things like Kafka or SQS queues) are better understood in terms of the base computing fundamentals. The base unix tools define a clear set of capabilities we should be familiar with, & to call them just another abstraction, to focus on our own local platforms, ignores the base root that all computing so far eminates from.
This abstraction-relativism you present is highly dangerous. Arguing we shouldn't care about anything because there are abstractions everywhere ignores a realer truth, that some abstractions have been around & underpin nearly all systems & likely will continue to do so. We're only barely starting to play around with alternative conceptions, in projects like Fuschia. But this is a rare, novel, & just-emerging break from our common frameworks of computing. One that would behoove people to gain some competency in.
