I was just watching a video about the trilemma and had a question about Ethereum

I don't have a ton of in depth knowledge, but I'm trying to understand the scaling problem at a high level. I was just thinking about how we have a fuckton of validators, but we're still bottlenecked by processing one block at a time on essentially a specific schedule. Would it be possible to process multiple blocks simultaneously to speed up the process of getting blocks into place? There would of course have to be a mechanism to make sure that the immediate next block doesn't impact the following block, but couldn't there be some way to accelerate the speed of adding blocks based on perhaps the number of validators or quantity of transactions pending, in order to allow L1 Ethereum to scale better?
