There have been a lot of well publicized (and far more, not publicized) aviation “near miss” incidents in recent months.

The reason may come down to inexperienced new crews:

Many of the increased flights are being staffed and guided by less experienced crews. Early in the pandemic, carriers slashed staff and many long-tenured aviation workers retired, leaving carriers scrambling to hire and train thousands of employees as travel demand rebounded.

There have also been some issues on the air traffic control side – is ATC understaffed and/or rushing out new controllers too quickly?
