Instead of focusing on tattoos, could we work on this being used for bistable displays, like e-ink but using light pulses to transition each pixel?

So much hype in the article and in the paper for it being "programmable" when it's just... UV reactive? Like, cool but calm down
> In outdoor daylight conditions, including shade, the UV content of incident sunlight is sufficient to activate PhotoTat to a photostationary state

Your auto-immune system does not like ink.

  You don't have an "auto-immune system". Auto-immune means your immune system is attacking your own healthy cells.
  Tattoos are fine. There's some evidence that maybe, maybe, immune system responses can be impacted by tattoos. But changes in immune system response does not necessarily mean impaired or negative.
