In the home cook world I guess? In professional circles he's respected within his niche (making advanced technique accessible to home cooks) but not particularly influential beyond that.
IDK if he made techniques accessible. I found his content interesting but pretty over the top. His stuff feels more like myth busters for cooking. Entertaining possibly educational but idk how its always practical. He has some thing about tonkotsu ramen, that it needs to be this big two day boil event. Emphasis on need. I threw some pork bones in a pressure cooker and it was just as good.
