What does 'so thus' mean?

The phrase "so thus" is somewhat redundant, as both "so" and "thus" convey similar meanings of conclusion or result. "So" is often used to indicate a consequence or to emphasize a point, while "thus" is a more formal way to express a conclusion or result. In writing or speech, using both together may be stylistically unnecessary, as one Word typically suffices to convey the intended meaning.
