Lightning implementations exist and are fairly usable (although I've found there is some disagreement on e.g. public key format for peers). Check out the following:
Do these projects have the nicest UX? No. Is it fairly trivial to hook up a shiny UI to their RPC interfaces? Yes.
It's going to take a bit to roll out the infrastructure necessary, but a 1.7 MB block size is good enough until then. Especially if miners stop using ASICBOOST and mining near-empty blocks.
