For the most technical, what you guys think of this?
Ark looks very promising and I like that side effect of using Ark will be improved privacy, similar like Coinjoin is doing but offchain.
Yesterday I listened the interview with main developer Burak from Turkey talking on Bitcoin Takeover podcast.
He worked before on Liquid and on Lightning Network, and Ark was created as byproduct of new Lightning wallet, but he introduced a lot of improvements.
His reason for creating Ark is to make Bitcoin available for everyone, and I agree with him that that is impossible to do on mainnet or with Lightning:

Routing fees (at least in Lightning) are still very low nowadays, so I doubt that is incentive enough.
There will be incentive in Ark, same as in Lightning, and Ark will be compatible with LN from what I understand.
Listen the interview I posted above.
