By 2030 everyone will be so used to having their Tesla drive them around on autopilot that the thought of catching a jet with only one driver or possibly none won’t seem like a big deal.
The last pilot shortage EVER happened in 2019, it was the best 2 weeks of my life!
BTW, if you don’t think change can happen so quickly remember that the first iPhone was released mid 2007. Prior to that a “smartphone” was not much more capable than a Nokia 5110 but had a low res camera and you could type some notes on it. A decade later life without a smartphone is almost inconceivable.
