Adam's sciencey videos absolutely mop the floor with his cooking videos.
I like his cooking videos, I think he has some nice practical recipes and techniques and I appreciate his emphasis on home cooking and "quick and dirty" techniques, and I'm glad he made bank off of them.
But he's a far better journalist and science communicator than semi-famous internet cook. His whole career before YouTube was journalism and teaching journalism and his experience shows in the quality of his work. You can tell he takes the time to research his topics and report in a measured, accurate way. I especially appreciate his screwworm video. It would've been very easy to attribute the whole issue to DOGE's cuts, but Adam does a good job with the nuance of the issue and the various causes and history of the screwworm and emphasizing that this was in motion before DOGE while still giving them an appropriate amount of blame. His earlier science communication videos are also great. His video on mushroom production where he visits mushroom farms, his videos on grain where he consults agriculture professors, it's mostly very high quality and well researched.
It's also been fun watching him evolve and gain nuance on things and change his stances, like his reduction of meat and expressing regret at encouraging so many people to crank their ovens for a single pizza. It's indicative of someone who's genuine and trying hard to get at the truth of things.
TL;DR: Adam is a great science communicator and journalist. His recipes are pretty good too.
