We don't always know with surety the intent of the ultimate author: that is why we have halachah, and the ability to interpret, reinterpret, and introduce novellae by rabbinic decree.
Torah has frequently been reinterpreted based on new ideas and halachah emended to deal with new concepts and changing ideas.
You don't have to like or agree with how such reinterpretations are done in communities other than your own today, but it is simply historically inaccurate to say it has not taken place, and textually dishonest to try and read it out of Gemara and later halachic writings.
Torah is never reinterpreted by new ideas.
The morals, principles, and ideas are constant, and never changing.
Applications may change based on changing technology.
For example, they didn't have airplanes, cars, ultrasound, etc in those days.
However, the same ideas and principles are applied to changing technology. The rabbis figure out how.
Also, in judaism the earliest rabbis in the Talmud have more weight than the next generation, that generation has more weight than the next generation, and so forth.
