Confessions of a researchaholic

Throughout my research career I have been very conservative in recruiting PhD students, especially for those whom I would be the (de facto) advisor.
(I am a bit more relaxed for hiring interns as the collaborations are shorter term and thus the risks are lower.)
I prefer to have deep involvement for each student and project, and the cost of having a student not suitable for independent research is higher than the risk of occasionally passing on a top candidate.

However, there are other professors/researchers out there who have been very successful in managing large groups.
So definitely go for that if your style is like a VC incubating startups, you have enough funding, and your projects require teamwork (e.g., one student probably is not going to build a new operating system or programming language).

Writing is an important skill for not only publishing and communication but also other career tasks. If you cannot do it for whatever reason (language, habit, psychology, etc.) it is better to learn as soon as possible.

Nobody else knows your ideas and thoughts better than yourself. Writing by someone else is not very likely to accurately reflect what you have in mind.

If you find it difficult to express your thoughts, it can be a sign that the thinking is not clear enough and writing can help refine it.

Do whatever to come up with a first draft. Do not worry about nitty gritty details like grammar as long as your collaborators can understand what you are trying to say. We can iterate the paper draft together to improve the not only the writing but also our thinking and execution of the project.

CHI 2022 provides this medium post about giving a remote presentation as well as different styles ranging from very simple to quite fancy:

• Slides with talking head
• Slides and voice over only
• Slides in a news like bubble
• Slides with a lot of post production
• Slides on VR presented in VR

Feel free to pick a style you like.
I would do voice over only as I try not to let people know what I look like, or even sound like via synthetic voice over.
But if you like people to know you and/or have the talk video better approximate an in-person conference presentation, consider showing your face.
