Cardano has spent a long time optimizing for the blockchain and not enough time optimizing for economic activity.
PoS, the eUTXO model, native assets, formal methods, decentralization, governance, research, scalability work, etc have all been core focus areas.
In contrast, the L1s that pulled ahead aggressively competed for developers, stablecoins, liquidity, trading, lending, payments, consumer applications, interoperability, institutions and most importantly: USERS
Cardano has treated adoption as something that will emerge from building superior infrastructure rather than something we needed to deliberately engineer.
It needs to be easy for builders to build and users to transact.
We need stablecoins, liquidity, distribution and applications people WANT to use.
We need to realize that these things cannot come second to the technology,
THEY ARE THE POINT OF THE TECHNOLOGY.
