I doubt it. Back then, TON (Telegram's "The Open Network" Blockchain) was hailed to be Solana's "successor" or "killer" only to fail in the long run. Sometimes marketing/PR matters most than the underlying tech of a cryptocurrency. In this case, Solana has better marketing than TON. But the latter has better tech. Especially in its approach for scalability.

I believe the "Solana hype" will last for quite some time. After all, "meme" coins are getting popular on the platform. Not sure if SUI will be able to gather the attention of the masses, though. It's relatively new and widely unproven. Between SUI and Aptos, both are neck-in-neck in their use of the "horizontal scaling" technique. Either one of them could become the "next Solana". That's a big "IF" because of the reasons mentioned before. Crypto land often behaves in many strange and bizarre ways, so anything's possible.
