Would you prefer a time machine that can only go back in time or can only go forward in time?

On this planet its pretty hard to forecast if the future will be less fucked up that the past. But out of curiosity for future technology I would choose future :)

well, I’m a bit nostalgic about how everything was back then so I'd opt for going back in time :)

I prefer both options for different goals :)

Well, aren't we already going forward in time? I would rather go to the past, we are going to the future anyways ;)
