I think it is not realistic for now, although Solana is one of the most innovative and popular Blockchain Networks today, still, it doesn't guarantee anything, maybe in two years time when the market will experience another a huge activity like what happens in the previous months that time maybe that $1000 per SOL speculation can be achieved.
Speculation that is too big is also very lazy to comment on because it obviously takes a long time and is very tired of waiting, so the speculation doesn't need to be too big for Solana even though it has proven to be good and good in cryptocurrency.
