If the A320Neo can sort out the engines and they don't have a host of tech issues then I think the Max is going to get hurt as it is just lipstick on a pig.
However if the Neo starts having problems then the Max will be lauded as great new aeroplane and will still be flying around in 2030+ with no EICAS/No fly by wire/manual everything.
Meanwhile people will still be writing articles about autonomous aircraft being just around the corner
