I'll just to add to that by going back to what I've said earlier. I will hammer these three points over and over again. Blockchain is the database. The network is decentralized, but not all networks need to be. Cryptocurrency is the asset to help fuel or power the decentralized part of the network.
You can have a blockchain database that is not decentralized and is extremely efficient and fast because it doesn't have to validate, cross-validate and collaborate with all the other decentralized servers.
Decentralization is the network architecture and blockchain is the database, and then the cryptocurrency is the asset on that. As my colleague here was mentioning, there are multiple new technological efficiencies that are demonstrating the ability to create a decentralized network while increasing speed.
Like anything else, technology evolves. If we look back 10 years at autonomous vehicles and AI, etc., we can't say that blockchain is slow and it stays slow forever. Humans and technology evolve.
