Realistically. Both sides have pros and cons.
Remote people are going to have to be exceptional at very visible and proactive work, or they will look like they are missing and it will stand out fast. A lot of people are good at this. But they will have a disadvantage of visibility and knowledge access.
Office people are going to have to make up daily lost time and productivity drains they will have by default. They start every day behind. They will have an advantage in access to resources, but at a cost in time and microtasking. Guarantee they will be taking work home to get some work done.
Both are going to coexist and do really exceptional things. But its up to the person how they work and if they are right for it.
If anyone thinks that informally staff who are good at their job and loyal to Dell are going to be passed over for someone who turns up to the office but cant do their job, they arent getting it.
This is a very smart move. Click that remote button and prove you can do it or hit the office button and be in some faces.
