Polkadot looks like a blockchain that can compete with ether. Gavin Wood has been working with Ether for a long time so the polka can be considered his version of Ether 2.0.
Maybe. But with so many competitors failing to take down Ethereum, I wouldn't count on Polkadot challenging ETH anytime soon. It's not about which blockchain has better features or user experience, but rather which blockchain remains decentralized and censorship-resistant.
No other competitor can outmatch Ethereum in terms of decentralization, reliability, and censorship-resistance. You can see why a new blockchain project like Solana faced a network disruption, putting almost everything down to a halt. If it were as decentralized as Ethereum is, it would've resisted such an attack. Low fees and fast transaction speeds are nothing if the blockchain is missing decentralization. As long as there are no competitors that are decentralized, Ethereum's position as the leading smart contract platform in the market will remain untouched. Just my thoughts
