Perhaps this is an age thing, but I've been (following) around technology long enough to know what's likely / possible, and a leap into a fully-visible hologram on a handheld device isn't likely in the coming few years (at the very least we'd see some precursors to it first). It's ok to feel indifferent, and you may even express that in person if someone is talking directly to you, but adding "meh" in a message you're choosing to write when no one asked you seems not nice to me. I'm not even insisting people don't do it -- I'm recommending one reflects more deeply before one speaks; it might seem hard at first, but with practice it will likely filter out unpleasant-to-others gut reactions you may used to have.
