I see it as part of increasing resiliency and data locality. A key characteristic is that the cost for data storage is shifted to the people who care about preserving that data.
So a good example is distributing Linux distro packages.
Apparently, cpu/mem can be tuned.

To be fair, ideas like can emerge all together, whether in parallel or because people were talking to each other about it.
Personally for me, I don't think web3 will get anywhere (and I could be wrong). I'm more interested in IPFS (and less so with FileCoin) because the use-case I am interested in is much narrower in scope. It's also interesting to me that "web3" got hijacked from semantic web ... though semantic web stalled out as well.
In this case, IPFS breaks the monopoly of trust (only obtaining content from a single source because that source is the reputable source for it). Content addressed data makes the source irrelevant. Many possibilities open from there (i.e. breaking the monopoly of storage).
