Answer: Tezos is a blockchain platform that has been designed to be resilient and secure, but like any other technology, it is not immune to external forces. The longevity of Tezos will depend on its ability to stay competitive in the ever-evolving blockchain landscape, as well as its ability to respond to changes in the external environment. While Tezos has been designed to be resilient and secure, there is no guarantee that it will always be here. It is important to remain aware of the changing environment and to be prepared to adjust accordingly.
