This is an interesting article: https://dba.xyz/a-bitcoin-l2-thesis/
But I have two objections.
#1: the author accuses bitcoin of having a "lack of programmability." It doesn't. Bitcoin Script is computationally universal because it has all the logic gates, and the bitvm whitepaper proved that you can get around the script size constraints by transporting state from one transaction to the next. So bitcoin script is fully programmable: anything a real computer can do, bitcoin script can do. It just requires lots of transactions (i.e. it's expensive).
#2: the author ignores the lightning network on the grounds that he wants to "mostly focus on fully programmable L2s."
But the lightning network is just as programmable as bitcoin is. A lightning transaction is just a bitcoin transaction that you haven't broadcasted yet. So you can do just as much programming therein as you can do in a "regular" bitcoin transaction, and even create a bitvm-like chain of transactions executing a complex program, all built on a lightning transaction and therefore on a layer 2.
I want to see work done in that direction.
