Personally, I think they overestimated the value of primate intelligence (disclaimer: I read a lot of EliteTrader, so I might be biased.) and underestimated the power of having an internal thermonuclear reactor. https://www.theringer.com/movies/2021/4/5/22367270/godzilla-vs-kong-scientists-paleontologists
At least these two scientists did not utilize taxpayer dollar sweat equity to think about the concept. Remember this shit below...? https://www.scientificamerican.com/article/no-death-star-for-us-military/
Godzilla would win with a direct blast of fire breathing. I watched the most recent film. I still prefer the orginal. The best Kong only movie was the one from 1976 with Jeff Bridges and Jessica Lange.
