> IPFS is unworkable... making it usable in the next few years
Absolutely not.
The OP brings up a lot of great, useful feedback for us, and we'll respond to it.
But the OP is also simply wrong in saying it's "not usable". There are millions of end users benefiting from IPFS, 100Ks of libp2p nodes, we see PBs/mo of traffic in the infrastructure that we run, and millions of daily requests to our gateway. Look to fully decentralized applications and systems like OpenBazaar, Textile, Dtube, and others.
Beyond that, we're well aware of the many shortcomings, and working on them. We're unfortunately spread thin across a lot of projects (IPFS, libp2p, filecoin, ipfs-cluster, etc), but each is seeing significant growth and improvement.
