Where contracts fail, and runtimes/chains are needed

• offloading long-running tasks (off-chain worker)
• changing underlying systems (e.g. the consensus protocol)
• writing the runtime in another language that compiles to wasm (even though it is an exotic example I could see this being relevant for non-rust devs in the future)

Interesting ideas, thanks for sharing!

• indeed, although I would actually mention things like on_idle or upcoming #[pallet::task] as they are more specific to a chain. Offchain worker is somewhat of a poorly understood concept and sometimes misleading. But indeed it is also unique to a runtime.
• indeed, if you want to change anything in the system itself, you need a chain. Very similar to VPS vs dedicated hardware.
• I do think you can have any language to also transpile to Solidity or compile to EVM byte code, so I don’t find this one unique to runtimes/chains/FRAME.
