a) By no means heard of them: http://l2beat.com
b) No, in reality L2s are accelerating in utilization, adoption and innovation that isn’t doable at Layer 1. The times of L2 are simply starting and about to blow up. We’re transferring from a monolithic to a modular structure.
c) Studying their observe, their technical and factual understanding of what an L2 is is so incorrect that I wouldn’t belief them as undertaking builders. My guess is that they’ve realised they don’t have the chops to construct a safe roll-up, so that they’re pivoting to one thing else and have made up a narrative for his or her buyers.
d) They’re not even constructing an L1 both however searching for to turn into a Polkadot parachain, which is basically an L2 structure. You’ll be able to’t simply turn into an L1 in your personal proper as a result of now it’s essential discover a answer for safety. That is non-trivial.
TLDR: I wouldn’t take these guys severely and their prediction of the demise of L2s is wildly misguided or is simply deliberate click on bait.
