As you can see from the GitHub ranking, Ethereum is ranked No. 55 Globally, ahead of huge established corporations! It is ahead of Automattic (WordPress), Google Cloud Platform, and even Amazon Web Services Labs (AWSLabs)!
In fact, Ethereum is the only Blockchain ranked in the top 100!
What this shows is that Ethereum has a massive base of developers working on it. When so much intellectual capital is poured into Ethereum, the likely result is that Ethereum will be successful!
