My Theory on high ETH Gas fees

I know the network is getting busy with NFTs and DApps… But ETH 2.0 is coming soon and Miners won’t be as profitable as they used to be right? So right now is the gold rush to mine ETH with crazy high gas fees before ETH 2.0 rolls out.
Please feel free to debate this. Is just a theory…

PS… why transferring ERC20 tokens are way more expensive than ETH itself?
