Highly related: What can we do about the deteriorating quality of questions?
This related question was asked over five years ago, and the situation has not improved. My perception is the opposite: A marked decrease in question quality all across the science based portions of the SE network since the decision was made to double the point value awarded to questions. This decision has encouraged people to write very low quality questions.
Bad questions will drive good answerers away.
I am on the verge of being driven away, in part due to the marked reduction in question quality, in part due to other bad technical decisions such as copyright, and in part due to the terrible treatment of SE moderators. I have noticed a drop-off in activity by other highly rated answerers. Doubling the bonus for asking questions is not the right answer.
The downvote penalty was not enough five years ago when the related question was asked, and now that minor penalty has been watered down even more. My modest proposal: Triple the penalty for downvotes.
