Libra, recall, is the new global digital currency being proposed by Facebook and others. Here you will find a link to the Libra White Paper and to rather more than you might have expected. There are also technical papers, such as The Libra Blockchain, and also Move, a new programming language, and also state replication using LibraBFT. If you want, you can clone the Libra repository, run your own 'core', and try your first transaction. For the non-technical, there's also Libra the organization, and the conditions for being a founding partner (tl;dr: you have to be wealthy and influential). All this tells me that Libra isn't going to just go away, and moreover (and this is key) it isn't going to limit itself to financial transactions.
