Monero is currently pushing ~43% of Bitcoin daily transaction without breaking a sweat. I don't see anything crumbling. Neither Bitcoin, Monero, nor Lightning can scale to billions of users and it may never be possible (or necessary) for them to Yes, we all know it's impossible for anyone else to solve problems outside of Bitcoin. It's a law of physics. I can't even make a turkey sandwich unless Bitcoin does it for me
With monero the whole blockchain needs to be used to find your transactions as they can be in a random chose address on the blockchain. So I don't think that I can prune anything because I would litterally prune one of the essential privacy features of monero. But I can be wrong so call me out if this is the case.
Kind of true. You can't prune to the same extent as other blockchains, but you *can* run a pruned node a fraction of the size of a full node. I've heard some say it is technically closer to "sharding" not pruning.
