If you stick with a PIN, law enforcement would also be stuck under the proposed system. iPhones with PIN codes are actually hard to hack by guessing randomly.
I put in 32 GB of DDR4 3200 RAM for $100 in my desktop. There's really no reason not to do it if you can swing an extra fifty bucks over 16 GB even though, yeah, 32 GB is overkill.
The hidden issue with the MAX was the lack of adequate pilot training. Nothing I say is meant to vindicate or defend Boeing. But much of the growth are in foreign low-cost airlines that save money on maintenance and pilot training. (An improper activation of MCAS would mimic a runaway trim, which is a condition that all pilots are supposed to recognize right away, and the solution is the same: turn off the automatic stabilizer trim.)
The MAX crash on Lion Air was caused by a defective AOA sensor. The part was known to be bad, and supposedly replaced before the final flight. The flight before the doomed one saw the MCAS trigger but the crew knew how to deal with the problem. They turned off the trim system and continued to the destination. However, the crew of the doomed airplane kept on fighting MCAS instead of turning off the trim system.
The Ethiopian Air incident saw the crew react properly by turning off the electronic trim system when MCAS activated. However, the crew accidentally got their airplane flying too fast so they were unable to manually trim their plane up. The last thing they did was to turn on the electronic trim system again hoping to use it to trim up, but MCAS fired again and killed everyone.
Again, Boeing really fucked up. Using only one AOA sensor? Allowing the system to trigger an unlimited number of dives? Giving the system the power to almost fully deflect the horizontal stabilizer? Hiding MCAS from pilots? All of that was incorrect. But Lion Air wouldn't have happened if the defective AOA sensor was correctly replaced.
The airplane in question is a 737-800, not the MAX. The plane basically went straight down into the ground. MCAS would have caused a rollercoaster pattern because the system only activates for a few seconds at a time. I can't even imagine what would cause a plane in cruise to dive straight down like that.
