The OnePlus tablet 4 would be amazing if not for the corners they cut..
Yes? In practice once you convince them to get into the plane the only real issue in the air for those new to flying is air sickness.
Also fun fact a good number of pilots claim to have a fear of heights (never met one irl except online in aviation forums).
If you are in aviation/aerospace, don't be afraid to share the joy of flying. There's nothing quite like cruising at 90-100 knots @ 3000-4000ft AGL on a nice clear day.
On the engineering side you can look up ETOPS and the various ICAO and FAA and EASA standards for airliner class aerospace engineering https://en.wikipedia.org/wiki/ETOPS
Trust me, y'all think airplanes are "safe" because of some sort of magical protocol. No single protocol actually works. It's mostly lots of layers that are stacked on top of each. It's why in aviation, catastrophic failure modeling uses something called the Swiss Cheese model; you need every single hole (error or failure) to line up to generally trigger a complete breakdown in safety. It may sound counter intuitive, but by aviation safety philosophy, a canvas and wooden frame plane operated under commercial standards and kept to a strict inspection schedule is "safer" than e.g. a privately operated 737 that doesn't follow manufacturer maintenance standards.
NASA has plenty of guidelines for writing "safe" aviation software. I doubt any software engineer will be willing to entertain the level of effort and certification needed to comply with those for e.g. their Django side project.
Aviation safety discussions on hacker news have barely more more depth than biotech and healthcare discussions here. It's extremely ironic because a tremendous number of pilots are engineers, and especially software engineers. It's not exactly a cheap hobby. But you don't see massive numbers of English majors come crawling out of the woodwork to join a discussion on the safety of C++ vs Rust, but tech bros flock to worshipping aviation as a platonic safety idol like moths to a flame.
(According to the Wall Street Journal)
Abliteration is a very simple technique. You just send in input sentences that it will refuse and then observe the residual streams and then zero out the refusal vectors. It's not some sort black magic.
People like to say that the tech industry is young but most don't realize that general aviation is only a few steps removed from the early days of Wright Brothers and their contemporaries like Dumont and Blériot. It's mostly civil aviation and military-adjacent aircrafts like the X experimentals that are truly pushing the boundaries.
It's a pity that clean sheet designs of airplanes made from composites (most famously your Diamonds and Cirruses) are dreadfully expensive to maintain relative to the old school aluminium frame designs. The composite (carbon fiber polymers) airframes have way better aerodynamic characteristics and benefit a lot more from the past 50 years of aerodynamic advances. Though given the fact that modern EVs have very aerodynamic external aluminium shells, I wonder if some of the limitations of shaping aluminium into complex aerodynamic shapes have been resolved (composites are much simpler to shape, they are basically fabric version of 3D printing).

I am still waiting for them to put their money where their mouth is.
