Polygon helps improve and simplify the experience of developing decentralized applications while allowing its users to fully benefit from Ethereum's network effects. The existing projects developed with Polygon will help ensure continued relevance, engagement, and utility.

As Polygon focuses on providing greater developer support for ETH compatible applications and resources, it's safe to state that the eventual proliferation of eth2.0 will likely help Polygon further its impact and engagement rate.

So, I think Polygon will be relevance.
