Technology will be somewhat important but not really as crucial as most think. As I wrote in the last post, Ethereum killers have similar consensus algorithms, and thus they tend to work in a very similar fashion. Of course there's the issue we've already discussed: high-throughput "monolithic" L1 (SOL) vs. L2-based "modular" platform (Ethereum, partly also XRP which is implementing smart contracts on a sidechain). And with the emergence of Solana and now also Sui also different smart contract languages are competing against each other, while previously everybody tried to be compatible to EVM/Solidity.
What I guess is also that some of the Ethereum projects will fall behind again after a market shakeout eventually. There will be perhaps 4 to 8 leaders which can grow further, and the others will tend to stagnate. This is due to the fact that human attention is limited, and thus too many "brands" will also clutter the space. This doesn't mean that the smaller projects can't be successful, only that even in a bullish market for smart contracts, and despite of the "levelling out" I described, some platforms will have more success than others, there won't be 10 or more platforms with a similar marketcap.
Also much depends if a "killer app" for smart contracts can be found which is relevant for everyday people and not only for traders. If this happens, then I think the market will be much larger, and more blockchains will be successful.
