2020s: Who do you think will dominate this era? I think this will be the Nikola Jokic, Giannis Antetokounmpo, & Luka Doncic era. Honorable mentions: Joel Embiid & Jayson Tatum. Do you guys agree?
2030s: I believe this will be the Victor Wembanyama era. But who do you think will be his main rival?
His main rival is likely 2-3 years away from being in the NBA.
I think you are taking way too many liberties to include Hakeem and Steph in their respective decades, both of which were dominated by MJ and LeBron, respectively.
