In hindsight there's an obvious evolutionary pathway from the Wright Flyer to Gemeni/Apollo/Soyuz.. but at the time in 1903 there absolutely was not, and anyone telling you so would be a crank of the highest degree. So it may turn out that LLMs have some place on the evolutionary path to AGI, or it could turn out they're a dead end like Cayley's ornithopters. Show me AGI first, then we can discuss whether LLMs had something to do with it.
In order to get to space, you must first be capable of flight through the atmosphere. That should be apparent to anyone even then because the atmosphere is in between space and the ground.
Regardless of whether spaceflight is still 1000 or 100 or 50 years away, you are still closer than you were before you demonstrated the ability to fly.
