There is nothing impossible in the crypto world, "Tron replaces Ethereum" might happen, but it will really take a very long time in my opinion, remember Ethereum is the favorite altcoin of many people, regardless of its shortcomings.
Indeed, but for the near future I don't think it can. because the platform from ethereum is still widely used by the new ProJeck project and also the ecosystem of this platform is also very large. to be able to replace it in the near future is impossible to happen.
