What problems does it solve ? Who's problems does it solve ?
It is solving the problem of scalability. For reference bitcoin can only handle like 5 transactions per second and ethereum like 20 transactions per second. In order to get global adoption of cryptocurrency we are going to need to scale to handle more transactions.
I know - Some of this stuff gets very technical. It provides all the infrastructure for a blockchain. Think wordpress for blockchain developers. The programming language, Substrate, is written on Rust and is turing complete (Obviously). You can exchange information without the need of a third party (Polkadot is decentralized). All the problems of the current 'censoring' and datamining would be impossible in the network do to the possibility of anonymity.
Also, regardless of your feelings of how 'Useful' something is, the crypto market is worth 1.2T. There's millions to be made in DeFI and it's changing the world and propelling previously unknown people into some of the richest people on the planet. Kinda like the original internet, whether you want it or not its coming. Get on board or get out of the way.
It isn't about being technical. It is about explaining why rather than what. If I started talking about cuckoo hashing before explaining that I was providing an associative container, it'd read weird. Similarly, one can fully understand the technical jargon and still come away from that material with "but why".
> Get on board or get out of the way
See, this is the stuff that makes every else get aggravated by cryptocurrency startup culture.
