"Netflix's Unnecessary Action Sequel: A Glimpse of Scientific Accuracy"

The 2015 film Terminator Genisys features a plot twist where the protagonist, John Connor, becomes a time-traveling villain whose body is replaced entirely with nanobots. While this concept is purely fictional, emerging technology in the field of cancer immunotherapy is allowing scientists to replace immune cells called T cells with engineered ones known as CAR T cells. CAR T cells are showing promise in treating blood cancers, and researchers are also exploring their potential for solid tumors. Unlike the immortal nanobots in the movie, CAR T cells are not long-lasting but can persist in the body for years, helping to detect and fight cancer.
