I rather like Rusty's Great Script Restoration Project. Not yet at BIP status AFAIK.
Otherwise, OP_CAT would probably be my favorite one-off opcode to reactivate.

Got in line for automated passport control. Guy in front of me puts his passport in the scanner. It rejects his passport. He tries a few more times and then the whole machine crashes.
Then he moves left to the next machine and repeats the process until it crashes. Guess what her does next?
This dumb motherfucker ends up crashing all 4 passport control machines and even though they rebooted, the passport software didn't come back online.

My long-term Bitcoin concerns mostly revolve around apathy.
What if not enough people care to self custody?
What if not enough people care to enforce the rules by running nodes?
What if not enough people care to put in the hard work seeking consensus for improving Bitcoin?
The most important thing is that we continue discussing Bitcoin. The exchange rate is merely a SIGNAL that we have done well SO FAR.

Thoughts on Trezor Safe 5 and Ledger Flex:
I like the UX improvements on both devices.
Nice improvements to Trezor's security model with Safe 3 and Safe 5. The addition of a secure element mitigates the old physical seed extraction vulnerability. Also, the chip in the Safe 5 mitigates glitching attacks and has additional anti-tamper features.
Safe 5 screen is slick and touchscreen + haptic feedback work exactly as I'd expect.
Ledger flex e-ink screen is also nice and I really hope the longevity of it is better than what we saw on Nano S devices with many experiencing screen failure after a few years.
On the complex bitcoin transaction signing performance side, Safe 5 is the fastest Trezor yet and is only exceeded by BitBox02.
Ledger, on the other hand, is looking to have worse signing performance than the Nano S Plus. SAD!
Props to both Ledger and Trezor for shipping new hardware that is compatible with existing APIs and SDKs. As a result, these devices were automatically usable with Casa's software!

Eastern TN, Western NC, upstate SC are rekt. Hundreds of roads in Western NC simply no longer exist.
The state and federal response has been ongoing, with over 1,000 personnel, including National Guard assets, deployed according to FEMA. A disaster declaration for NC has been made but crews cannot traverse over collapsed bridges and 100+ foot ravines.
Main interstates I-40 and I-26 have collapsed sections. Numerous state roads have washed away.
Many secondary roads into neighborhoods are effectively eviscerated for miles. Survivors can't get out, help can't get in.
It's hard to get into Asheville. A 30 minute drive take 8-12 hours with many roads not existing, the remaining gas stations swamped. To get into smaller towns in the mountains is a day's journey if possible at all. National Guard trucks with food and water have to stop at collapses.
Similar to Hurricane Katrina, where boats and helicopters were the only viable means of aid delivery in the first days, air support is currently the most effective way to connect Western NC to the outside world. There are a limited amount of helicopters operating. Although the water has receded, the roads are still impassable.
This is still very much an active search and rescue mission. There is a high number of missing (in the thousands per state media) because people can't get in touch with loved ones. We saw this after Hurricane Ian as well, and expect that number will drop significantly when phone service/internet returns. For death toll and recovery, the final number will likely not be known for at least a month.
The lack of media presence on the ground isn't for lack of trying - reporters can't get into many areas for the same reason rescue can't. Even if they could, communication systems are destroyed / offline.
This is not going to be a quick recovery for anyone. Some rural parts of Western NC may never be rebuilt.
