Segwit adoption plateaued around 60% and has been steadily decreasing ever since. It's a piss poor substitute for real scaling by increasing the block size like Satoshi had intended. Even if it had been a good idea, the core devs butchered the implementation.

Not even close. The lightning network is the ultimate vaporware. It was promised as the solution to Bitcoin's scaling problems NINE YEARS AGO ( https://twitter.com/starkness/status/676599570898419712 ) and is to this day considered unsafe and "experimental". It failed to deliver on just about every promise it made. Even the core devs have abandoned it for Liquid.
> No mention of sidechains like Liquid
Finally, we get to see the reason that a handful of Bitcoin core devs have been holding Bitcoin hostage for ten years. Liquid is a centralized Bitcoin sidechain that allows exchanges to pay extra in order to clear their transactions faster than would otherwise be possible on Bitcoin's now neutered base layer. Liquid was recently criticized for being fundamentally insecure after this embarrassment ( https://www.coindesk.com/blockstreams-liquid-network-sent-8m... )
> No mention of Taproot.
Wake me when it's merged. The sad truth is, ever since some of the core devs formed Blockstream and hijacked BTC, they have added almost no new features on the protocol level. The only one they were willing to work on is Segwit and only because it solidified their power over BTC. They have no incentive to make BTC better. If BTC worked well, nobody would want to buy Liquid.
Let me know when any of those things are used in a significant amount by real life, in person merchants....
Because right now, the only merchant point of sale system that has any non-negligible amount of adoption, is BitPay, and the only thing they might be using is Segwit, which gives pretty minimal fee savings.
They aren't even close to using anything like lighting, or liquid, or any of that other nonsense that is not implemented by any significant payment processor, or user wallet with any significant amount of adoption.
Satoshi is great proof that you don't need to know everything to understand something enough to make something, read some David Deutsch.
