What most people don't understand is that merit and popularity are two completely different things. And they will always find these technical rationalizations for why one things takes off and another doesn't. But it's all side issues and the technical merits often barely matter to popularity.

For example, the new "cryptocurrency" Libra being promoted by Facebook and supported by Visa, MasterCard and PayPal (sworn enemies of cryptocurrency since it completely invalidates their business model) has got to 5,437 stars on GitHub practically overnight.

Yet there is some technical debate as to whether this is even truly a blockchain technology in the end due to the closed validators and reliance on fiat.

But if Libra launches, it could easily become the largest market cap, just by virtue of being inside of WeChat/Facebook.

Assuming Libra goes forward, for Ethereum to have a chance to take off, Ethereum 2.0 needs to complete its scaling upgrades and launch before Libra. And what they need to be popular is just to be attached to something trite but addictive (like Facebook). So to accomplish that, having a simple library that developers can use to embed a lightweight wallet in a mobile app, perhaps something derived from nimbus, so that a mobile app with a normal install process can contain Ethereum. Once the scaling is available, all it would take is one popular game to use it for micro-transactions, or a popular chat app to embed it. Or it could be anything as long as it's popular. For example, a NSFW apk that had to be sideloaded and has a library of Ariana Grande and other celebrity upskirt clips clips, that uses Ether subscriptions to unlock exclusive softcore smut. Just any garbage that lots of people will get off to. Like Facebook.
