Edit: I should add, I do get 4K120 VRR and HDR on the M1 Macs when connected to a monitor via Thunderbolt or Thunderbolt to DisplayPort adapter, and I would expect a Steam Machine to be similar using DisplayPort, but my TV only has HDMI input and so can’t work in this mode (and a Thunderbolt to HDMI adapter doesn’t work either).
I think the author is walking a tightrope between convincing the reader that she wrote this herself and that there's more depth to her than what we see on stage or in pop media. Writing this blog is definitely a tougher assignment than doing podcast interviews or behind the scenes videos.
You are right, of course, a good editor could make this better, but I think she's deliberately avoiding that here. A pop star is unwise to fire a good producer without a better replacement, but sometimes they have to bring out the piano and do an acoustic performance live.
