Here are some quotes of people complaining about "youngsters these days".
1. The world is passing through troublous times. The young people of today think of nothing but themselves. They have no reverence for parents or old age. They are impatient of all restraint. They talk as if they knew everything, and what passes for wisdom with us is foolishness with them. As for the girls, they are forward, immodest and unladylike in speech, behavior and dress.
2. The children now love luxury; they show disrespect for elders and love chatter in place of exercise. Children are tyrants, not servants of the households. They no longer rise when their elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize over their teachers
3. I see no hope for the future of our people if they are dependent on frivolous youth of today, for certainly all youth are reckless beyond words... When I was young, we were taught to be discreet and respectful of elders, but the present youth are exceedingly wise [disrespectful] and impatient of restraint
#1 was written in the 13th century, #2 in the 5th century BC and #3 in the 8th century BC. Old people always think young people are worse than ever.
I say this not to invalidate your feelings of frustration with how people are coding these days compared to the good old days. But ask yourself if your skills haven't improved in that time. Bugs that you would miss 10 years ago are now obvious to you. Also, there's just a lot more code out there than there used to be, judging by number of repos. The friction to put something into a public repository is lower than ever. That gets us some gems that might not have existed otherwise, but also some turds.
Rest assured that 10 years from now, devs will be talking about the good old days of today and how much better it was compared to 2030.
