Whether or not inflation theory holds long-term, I highly doubt that "most of current research will prove itself completely useless." Even if Dark Energy process to be done yet-undiscovered property of ordinary matter, the research on its effects and properties will still be very valuable. We didn't throw out Galileo's research when Kepler discovered new principles, or Newton's when Planck and Einstein performed their research.
