Safer in a health sense, but I fear once Academia realizes that lectures can be recorded and supplemented with some office hours for questions. The life of an academic will become tenuous..teaching in real time over Zoom is only a short order of magnitude above a well structured pre-recorded lecture series. At least in my experience.

Universities have figured this out a long time ago, and have been cutting all sorts of corners in instruction (Despite the growth in tuition.)

The life of an academic is tenuous already, and a lot of instruction is done by poorly-paid, untenured sessionals. Tenured positions are in 2020, rare as hen's teeth.
