The post highlights the complexities involved in creating gas turbine engines, primarily due to the physics of high-altitude flight where temperature limitations complicate efficiency. User comments suggest that electric aviation may offer solutions that traditional gas turbine engines cannot, such as higher operational altitudes and reduced temperature constraints, leading to potential improvements in overall efficiency. The comments point to a misconception that electric systems face insurmountable energy input challenges, while in reality, they could leverage physics to achieve significantly better flight performance.
