**What happened:** A Reddit discussion sparked debate about Bitcoin's technical limitations, questioning why the network hasn't integrated modern blockchain features like native scalability, privacy, smart contracts, and energy efficiency that newer protocols have adopted. The post highlighted seven key areas where Bitcoin could theoretically improve but hasn't.
**Why it matters:** This touches on Bitcoin's fundamental design philosophy versus practical evolution needs. While Bitcoin maximalists argue that ossification preserves security and decentralization, institutional adoption increasingly demands features like programmability and energy efficiency that competing networks offer natively. The discussion reflects growing tension between Bitcoin's "digital gold" narrative and its utility as a modern financial infrastructure. Layer-2 solutions like Lightning Network attempt to address some limitations, but they introduce complexity and trade-offs that don't satisfy all stakeholders.
**Context:** Bitcoin's conservative approach to protocol changes stems from its proof-of-work consensus model and the high bar for network-wide upgrades, requiring broad consensus among miners, developers, and nodes. Recent years have seen minimal core protocol evolution, with Taproot being the last major upgrade in 2021. Meanwhile, newer blockchains launch with advanced features built-in, creating competitive pressure but also highlighting Bitcoin's "lindy effect" - its proven resilience through unchanged fundamentals.

• **Lightning Network adoption metrics** and whether Layer-2 scaling can satisfy institutional demands for programmability and throughput
