There are bridges to and from Ethereum right now. I use them every day because I need a fast sidechain for my application.

Choosing ETH2 is predicated on the assumption that ETH1 will be bridged more cheaply and easily than existing bridges can provide and that the opportunity cost of waiting is worth it.

I had to make that decision personally, decided I can't wait for ETH2, so we're using a bridge that's available today and building an ecosystem elsewhere.

Several other product leads that I know are making the same decisions, they can't just put their lives on hold and trust that ETH2 will solve problems for which there's no public timeline or even a public solution.
