$DOT The success or failure depends entirely on whether JAM can land, and whether there is a team that can really use it to create something "disruptive" after landing.

Personally, I believe that heterogeneous multi-chain will definitely be the final form. The design concept of Polkadot is correct, but it has placed a task that is rated 10 stars in difficulty at the first step. If it can survive the 2026-2027 critical window of "either breakout or exit", there is still a chance for a comeback in the future; if it cannot survive, it will likely end up like EOS and Cardano, becoming a "once very promising" pioneer.
