Probably not, that is why people are looking to "3rd generation" blockchains for solutions.
The 3rd generation blockchains aren't actually traditional blockchains at all, but mostly new technology.
Projects like byteball, nano, and iota use very different ways to approach the decentralized p2p open source ledger.
Mostly they have been successful except maybe iota.
Nano at least is fully functional, it is instant, has no fees, and scales infinitely.
Try it, you will never go back to normal blockchain again!
But I don't think this means that blockchain will become obsolete.
There are so many other applications of blockchain tech, just day to day payments aren't practical.
Agree. I believe that the new trend is not Blockchain itself, but rather a Directed Acrylic Graph (DAG) which provides infinite scalability for the world. This solution seems ideal as transactions can be processed instantly and without fees. Cryptocurrencies such as Nano, IOTA, ByteBall, Constellation, Coti, and Hedera Hashgraph, use this innovative technology which is far superior than Bitcoin's blockchain tech.
If such cryptocurrencies become practical within the mainstream world, then they could easily surpass VISA with their infinite scalability. It has been shown in IOTA that the more the network usage and growth there is, the faster the network will be. Which is why, it's only a matter of time before DAG-based cryptocurrencies could rival Blockchain-based cryptos like Bitcoin and Ethereum.
Despite this, Blockchain tech is still the norm these days due to its high-level security and popularity. Cryptos like Bitcoin and Litecoin will be used as a store of value, while DAG-based cryptos will be used as digital cash. Therefore, there's a possibility that in the future, cryptocurrencies could beat VISA and other traditional payment systems with their corresponding technical architectures (either Blockchain or DAG). Just my opinion
