I am an engineer who is not loved by the English, but I am forced to read vast amounts of English every day.

by computers.

-----

Once, when I was tuning the system at my wife's parents' house, my mother-in-law said to me, 'Well, it's great to read so many horizontal letters'

Oh, I see. I've just realized that this is also English.

But when engineers struggle with these messages from the computer, they am not 'reading' English.

They are 'observing' the word.

-----

They don't need to read the English that comes up on the computer console.

"Error", "unexpected", "unknown", "irregular", "suspended", "failed", "not found", "expired", "serious", "warning", "overflowed", "invalid", "too long", "out of range", "occurred", "dropped".....

In short, if they find any of the above words, they've failed -- that's all they need to know.

After all, "creating a system" means as same as

"They will just keep changing the way they do things over and over again until they don't see these messages anymore"
