Decentralization, in the crypto/blockchain/web3 sense of the word, is a crucial thing. Here is an excellent article talking about why it is the key innovation of blockchain technology and why it is a central feature in this new emerging web3 world.

But of course, it can all get very complicated. So I thought this -- and in particular the sentence in bold below -- was a good way of describing the benefits:

"...decentralization enables web3 systems to be credibly neutral (they cannot discriminate against any individual stakeholder or any group of stakeholders, which is critical to incentivize developers to build within ecosystems) and composable (to mix and match software components like Lego bricks). As a result, web3 systems function more like public infrastructure than proprietary technology platforms. In contrast to the gated software of Web2, web3 protocols provide decentralized internet infrastructure on which anybody can build and create an internet business. Crucially, in web3, this can be done without the permission of the original deployer of the protocol or the need to use a centrally controlled interface."

This resonated with me because think about how important public infrastructure is to our cities. Most of us take it for granted that, when we need it, we can just plug in and access electricity, water, sewer, and other public infrastructure.

But throughout history, these services have been fundamental to the growth of our cities. They empowered scale and better health outcomes, among other things. So it's exciting to think that we are now living through the creation of something kind of similar in tech.
