What will replace Solana?

I've been hearing a lot of buzz about Solana, but with the volatile nature of the cryptocurrency world, I can't help but wonder - what could potentially replace it in the future? Given its unique selling points like scalability and speed, is there any other blockchain technology on the horizon that could potentially overshadow Solana? Or is it more likely that we'll see a gradual evolution of existing platforms, rather than a complete replacement? As an expert in the field, what's your take on this? Are there any promising contenders emerging that you're keeping a close eye on?
