I think Qe8!? is too passive for the Dragon. White, in this computer game, appeared to have an easy time of it.
Who is using it? Or, is this a common line in computer games?

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

What do you suggest instead? Carlsen likes to play a6 (the Dragondorf) and wiki suggests Re8 but neither of those look particularly good to me. At least Qe8 gives black some drawing chances.

SF-dev eval for Qe8 is always >+0.7 and go to +0.98 at D=38..45
a6 is best move according to Komodo 9.3, but it fails-low in SF-Dev at D=38+
