Segwit itself provided an effective 2x increase in onchain transaction capacity and it fixed transaction malleability which was necessary for lightning network. Lightning network has 50,000+ open channels where payments can be routed without going onchain. Given the lightning network’s strict requirements to keep a node online & responsive, less you lose all your funds, I think that’s extremely impressive and shows a real demand for fast cheap payments.

Now, in November taproot/schnor activates which gives us ptlc’s on the lightning network as well as makes a lightning channel opening transaction look like a normal single signature transaction, yay privacy. All of this lays the groundwork for the next major base layer change, in probably ~2023, anyprevout. This will give us “eltoo” on lightning which is nirvana. Eltoo removes the penalty mechanism which makes running a lightning node on a mobile phone or home node much more reasonable.

Protocols take a long time to develop, especially ones where a miss-step could mean the loss of billions of dollars.

Do not believe anyone telling you that their coin solved bitcoin’s scaling problems years ago.
