Libra is not really a crypto-currency but rather a Facebook wanna be currency. It is highly centralized (as opposed to decentralized, which should be the goal for a true crypto-currency).
Libra’s tech, apparently, is not that impressive neither. In short, all Libra has going for it is the huge Facebook potential customer base. But if we think about it, what is the point of having a huge customer base if the tech can not even manage to handle a sizeable / scalable solid number of transactions per minute?
A large customer base alone does not guarantee the success of a tech project, let’s not forget about the recent fiasco of Google +1.
Use case wise, what is really the point of a Facebook coin? There is no need for it whatsoever. All the current transactions within FB can be easily accomplished via Paypal or Credit Cards in a very fast manner, without any need for a crypto-currency.
On top of all that, Libra is being heavily regulated, which will probably limit its (already quite limited) capabilities a lot.
Will Libra go far? It is very hard to predict the future but if Libra ever makes it, it will certainly have to overcome a very rocky start.
My own bet is on the 3rd generation crypto-currencies. I have my eyes set on Cardano (ADA).
