Exactly.
The complexity of a software should be measured by the average time a person need to completely read and understand it.
A simple software can take a day or a week. A very complex one, a month.
Everything above, is broken beyond repair.
Yes, we need to rethink almost everything from scratch.
Sounds good to me. I assume, the person being someone other than the author of the software.
But why do you conclude that this requires to rethink almost everything from scratch?

How many mainstream software did you try to read and understand completely in a month?
I do not mean "enough to hack them" but enough to predict where a bug is by looking at it at occurring at runtime.

I rarely look at mainstream software. I have looked at quite a bit of software that I would personally call complex, but none of it is mainstream.
I assume you mean that most mainstream software can't be understood completely -- with your definition of "understanding completely" -- in one month or less.
So when you say "rethink almost everything from scratch", do you mean "rethink the way mainstream software is written"?
It's just that "rethinking almost everything" is a very broad statement, so I would like to understand better what you mean by it.
