introducing additional features into Bitcoin that are increasingly complex
What do you think is increasingly complex? I think segwit makes Bitcoin simpler and safer. (though because the old things are still supported you can say there is some increase, but it seems pretty modest considering the simplicity it brings to people who are only using segwit and the number of problems it solves)
SegWit stores/broadcasts signature data separately from transaction data. Prior to SegWit, all of this was stored together, and I see this as two things that can potentially go wrong verses one thing that could potentially go wrong. If someone who is not using SegWit sends a transaction then the signature data will be stored along with the transaction data, adding to where fully validating nodes need to check when checking if a transaction (and block) is valid or not.
I also believe that many (maybe all) of the BIPs that have been implemented in the last medium term were implemented in order to allow for LN to be possible, including SegWit. (Yes some of the BIPs do solve other issues and are overall beneficial to Bitcoin). Based on my understanding of LN (from reading the white paper), I believe LN to be horribly complex because of the number of transactions that need to be signed in a very specific order by each party whenever one party sends BTC to another party via LN. I believe this complexity will result in wallets like electrum, multibit and armory to have bugs in them that go undetected that can result in the loss of funds by users.
Are you some kind of clairvoyant? You appear to be having troubling "visions" about Segwit/LN, based on your perceived complexity of these solutions, informed by your feelings.
If complexity were an issue in it's own right, Bitcoin 0.1 would never have got off the ground, the system has been complex from the start, and it needed to be to solve the problem Satoshi set out to solve.
You're trying to talk to a world-expert on Bitcoin about the way these changes affect your emotions. Don't be surprised if no-one cares.
