the only poor English is the use of "it's" where "its" is correct. "parent process" and "child process" are legit unix terms. As is "forking" (how a parent process generates a child process) and "orphan process" (child process that lives after its parent has died)
The parent / child contexts are used in a lot of other contexts like trees (including DOM), etc. so there are a lot of things it could potentially be talking about.
It could make more sense in another context though. Anthropomorphism itself isn't that weird, especially since it seems like this was written by someone who speaks English as a second language. Might not be weird at all in their own language.
