Nope, and here's why.
The current generation of blockchains (1) don't scale or (2) require centralization to scale.
But these first-gen blockchains that everyone's using -- Bitcoin, Ethereum, Ripple, Stellar -- either scale very poorly (BTC and ETH), or scale much better but use trusted servers to do so (Ripple and Stellar).
Another practical issue is: what about mobile? An Ethereum-secured mobile app would require the user to download over 1TB (1000GB) of ledger history just to get started -- not exactly feasible on a smartphone.
It's also troubling that ~6 people control the vast majority of hashing power on the Bitcoin network, for example, which means that, while Bitcoin's computation is decentralized, its power is even more centralized than traditional banking -- not exactly the solution we're all looking for, right?
Perhaps the next generation of blockchains will scale without introducing centralization and work well on mobile devices, but the current one doesn't, so for now, we'll pass.
