Do you think L3 networks are necessary? If not, why? Do you think they're overhyped? Your input would be greatly appreciated. Thanks.

Depends on the market mate. From the last bull run like 2020 the users increases until now. So there would be massive growth on users, in the future and I already uses L3 network and somehow they are efficient but not yet massively used compared to famous l2 like arbitrum and optimism. Plus there are more coming L2s, so I think its just an upgrade of L2s, some could say money grabs but yeah for sure some are for that but there are serious projects too build on L3 that solves such problem on the previous ones. So I think its better that we anticipated already the potential use later on at least everyone is ready when the time comes.
