The real purpose of this process isn't filtering out brilliant programmers but who are more obedience.
Managers aren't some kind of stale guy but predators who sucks slaves' blood. They actually know what they're doing, they're sending a powerful messages that they have power to order subordinate dumb things, like memorising riddles.
Make decision by considering blockchain as data structure of distributed resilient auto-clearing accounting system. I don't think learning that would make you more "technologist" if such system doesn't serve you any purpose, cryptography and data structure rather make one "technologist" in general.
Blockchain is not inherently decentralized. Decentralized consensus protocol is what makes Bitcoin decentralized and ineffective, Nothing to do with blockchain. Governments and big banks generally use blockchain with more centralized permissioned consensus for their infrastructures.
Database is heavily designed system, not a kind of data structure as blockchain does, so database is the one that's overkilled in this case.
Centralization and decentralization is not black and white, there's a spectrum between them. Permissioned blockchain can have enormous nodes, such as 10000 nodes, involved to achive consensus.
How do you make database permanent and achieve consensus between enormous users? You may end up with a data structure called blockchain and consensus protocol in that database with extra layers and barriers.
No, not really. The US financial system does it using SFTP and tech from the 70’s just fine.
All the stuff you’re talking about is only useful when it’s nothing but distrusted counterparties with no trusted intermediaries, no place anywhere someone can store a copy of the data they trust, etc. which pretty much never happens in the real world.
All these issues got worked out a long time ago in ways that really do work fine. It’s a bit slow, but it works.
Most of the things you’re talking about also have big disadvantages for real world players (no one generally wants all transactions stored forever and visible to everyone for instance, or for transactions to be immutable even if there was fraud or fat fingering).
Where it CAN be useful is where the existing power structure is actively trying to destroy trust in any active institutions or actively driving the economy off a cliff bandit style, but is also unable to clamp down on internet connections.
Which does have some niche uses, and it might be more than that at some point. But right now it’s just not well fit for purpose compared to the equivalents.
It depends expensive data centers, engineers and whole legal enforcement involving judges, lawyers, prosecutors, overseer, agents and jails to make public servants not corrupted. Even hiring one human are much more expensive than blockchain. Governments and banks research blockchain to reduce all these expenditure. Blockchain data can be updated with old data permanent at the same time, not a problem at all.
I honestly think you're not informed enough on this topic. What you are criticizing are mostly solved now. Gov and big banks are adopting blockchain opposite to your point.
Current Internet "works" in a very complicated way, ISPs and apps handle all the hassles, wire and wireless infrastructures, effective routing, certificate authority, encryption, permission control.
Clients who won't notice until they want to form a network at wild themself. In addition, average app developers are error prone at cryptography which are potential security holes.
Yggdrasil deals all of them as an all in one solution. Ad-hoc WiFi is enough to form a network. IP address is username, routing address and public key. App built on Yggdrasil is also freed from dealing with encryption and permission control.
Yggdrasil doesn't need Internet but existing IPv6/IPv4. Ad-hoc Wifi or local router with multicast support is enough for Yggdrasil to run automatically.
