I think that too: now it seems polkadot's time though. Dot adepts are being loud about the fact their platform will overtake Ethereum at some point.
Let them have 15 minutes of glory: on the long run, we all know what is the best asset to hold.
Any altcoin without unique real life usage is not going to thrive for long, and this is applicable for Polkadot as well. Eventually, Polkdot will lose most of its value and end up where Cardano is at right now. Overtaking Ethereum is never going to be easy, as they still have a huge monopoly in the smart contract platform sector. If the claim is just for hyping Polkadot, then I am fine with that.
