As long as you can control for fire, electrical safety seems like a temporary condition as robots and intelligent machines are cheaper and more available long term solution to hot swap blades in datacenter racks.
I think you're being downvoted for speaking of a complex future possibility ("robots and intelligent machines ... solution") as if it was a proven commodity. There will be many twists and turns in the path to the possible reliability, scalability, and cost effectiveness of robots and intelligent machines.
Appreciate your effort to provide reference info. Near the end it says "part of SoftBank’s efforts to implement robotic automation at [one] Data Center scheduled to start operating [no later than April 1 2027]".
They literally speak of preparing for a future that does not yet exist. I am optimistic it will exist, but that's not the same thing as it already happening and having a track record of reliability and profitability. I could find no mention of robots actually doing anything at that link. The article is about prepping servers, not specifically about robotics, in the same sense that planning hoses for gas pumps at gas stations is not about building cars.
But the discussion is about the safety of systems being actively implemented. For now, people are required to maintain data centers. Right now, these centers are transitioning to high voltage DC. Right now the best attempts at fully automated data centers are in progress with unverified status. So, for now we need to keep the humans safe. Future data centers not needing humans doesn't keep the current humans safe. Thus, optimistic future speculation is off topic and not relevant to the discussion of human safety with high voltages.
People are tired of off topic speculation masquerading as relevant to real world problem solving. It's not a hate boner.
EDIT: expanded to make it clearer why I believe the speculation to be wildly off topic for this particular thread.

What I'm hearing is that they've been trying to build a human-free datacenter for 6 years and they haven't done it yet. What's the betting that that "end of this year" schedule slips further?
