I'd have to go with the future. I already have a good idea of what the past was like and know that I would not fit in there. I'd rather discover what the future holds.

Unfortunately, 1918 wouldn't be all that much further in the past, but I'd take it. Some of my favorite people and all of my favorite music were in their prime then.

Past, I know what I know now. In 100 years I'll be too old to enjoy it But I'm sure you meant if age didn't change. Same difference, I'd be an idiot in 2118 not knowing how things work and I can dazzle people with hope of what's possible in 1918

Even though it would be interesting to experience the feelings at the end of the war, I would not want to stay long. Economy at a terrible low, grief and fear from the war, worldwide flu pandemic, and terrible conditions. I would like to see what the future holds. Hopefully, we haven't ruined our planet entirely by then.

Definitely the future because it hasn't been written yet

The future must definitely, if we're still here, I would love to see how far we're have gone.

Future. It may or may not suck but I know 100 years ago here did.

At the end of WW I the world went into a series of nasty dips. No thank you. I'd rather take my chances on the possibility that we have learned a little something by 2118.

Future for sure. Imagine the knowledge we will have.

Future.

2118, Because I know the past lets see the future

What woman or non-white person in their right mind would want to go to the past? Not to mention 1918--ring a bell? Millions die of influenza?

The fashion alone would be worth it for me. And if only have to wait a couple years. Also, it would give me plenty of time to ensure my prosperity during the upcoming great depression. Especially with all researched future knowledge...

It might be a toxic, radioactive future - we don't know. So I can't answer.

Remove all possibility of drumpy!

I love art deco and the 20's
As an educated cis white male with knowledge of the future I think I'd do alright (or drop dead of disease)

2118 because AI and robots will replicate and revive the environment; thus, preventing an extinction. I'd get a place on the O'Neill-1 cylinder, and migrate into space.

Future, maybe by then we will become a space society and I'd have hope of getting this miserable hunk of rock. This is on the basis we haven't totally devastated the entire plant and now the cockroaches are in the dominant species.

I can learn about 1918 in books but no one knows what 2118 will be like. My curiosity would definitely take me into the future.

In the past so I could be part of the expat movement in Paris

Well given that 100 year in the past would mean being in the run up to world war two and the rise of fascism, McCarthyism and the cold war, neither.

A hundred years ago wasn't that great of a time and at the rate and directions we are going a hundred years from now won't be that great either. I think I will just ride this train til it hits something.

The average lifespan 100 years ago was around 48yrs for a male, it's around 76yrs now... Hopefully a hundred years from now it's improved even more, I'd very much like to have as much time as I can get.

Future, maybe they will find effective treatments for my autoimmune conditions.

Neither.
