Layer 2 Scaling Solutions

Hello all,

From my understanding (which may be flawed) layer 2 solutions will compliment future success of Ethereum as transactions will be made on these chains. My question would be - do you see a future where multiple solutions exist? Moreover, Can we see chains that use optimistic rollups succeed more than zk rollups (or vice versa)? There are many different cool projects out there - and I am starting to see a lot of growth within development of these projects. Wonder what you all think. Thanks!
