As for positives I feel it could increase the amount of money spent on development of Bitcoin and Lightning as well as (hopefully) make Lightning routing profitable.

We see how centralizing it is on other chains when mining/validating/even hosting a copy of the blockchain CAN only be done by few actors due to resources necessary or IS only done by a few actors because there is no incentive.

I would love (eventually) a non-custodial wallet that holds Bitcoin, Lightning Bitcoin, and USD, with all channel opening closing and liquidity management to be done automatically. It would be huge for developing nations to be able to put what they need for the week to eat in USD and put the rest in Bitcoin, as one needs a guarantee of not starving due to Bitcoin's volatility.
