Bitcoin went on to create an entirely new industry employing tens if not hundreds of thousands of people, fund thousands of research projects and startups, create financial independence for thousands of people, allow thousands of people to transmit money in situations where it would have been difficult or impossible otherwise, and probably other things. It's a massive cultural phenomenon with global reach and real consequences.
The adoption looks different because it's not an apples to apples comparison. The appropriate comparison would be between "blockchain/crypto" and "cloud." In that comparison, the Dropbox equivalent likely hasn't been released yet. And even still, the technologies are different enough that I'd expect different timelines. The inherent difficulty of implementing cryptographic systems to the highest standards, and the regulatory hurdle implied by the fact that any token is arguably a security, matter.
Also, for what it's worth, you can send money to anyone in the world instantly now.
My personal opinion is that interesting things will start to happen after we realize there's an architectural sleight of hand in the "web3" vision and it doesn't really make sense. Projects that recognize this are already gaining traction.
