If the you of the past is now in the future, who are you?

If the you of the past is now in the future, who are you?

~~~ What makes you think that it is the same 'you'?
Because you are experiencing a 'memory' (thought/imagination)?
Surely we know by now how... creative... memory can be!?

The Present you

A Relic! I find myself there and here as I age daily!

If my past has gone into the future, the things would be in the reverse direction, which means I am now before my past. It means the past hasn't happened yet. then, my thoughts would be way before my past, I would be way late of time - I would be history by now (if that's the case).
I would be at a time closest to the beginning of the past, because the past hasn't started yet.
I would be a kid by then.

And colorless green ideas sleep furiously.

Look, I understand. It seems like a deep question. However, Analytic philosophy takes a dump on your question by pointing out it's meaningless, due to a linguistic trick it uses. We perceive sentences as making sense when they're correctly grammatically structured, but sentences can still fail to make sense when you unpack the semantics of their terms.

Your question is phrased like that. If we think about your question, it's not actually asking anything at all. It just pretends to make sense.

Let's take away the temporal terms: If the you of X is [the same as] you of Y, who are you? Easy. Identity is transitive- let's call you Z. So if Z = X, and Z = Y, then it follows that X = Y = Z.

Just because your terms are about time, doesn't mean they stop being attributes. Attributes are transitive across identity.

Now if you want to ask whether that's the case that you are you when I upload a copy of your mind to a different host! and forget to delete the source it came from... Well, that's a different question.

The me of the past is now in the present. There is no future yet. I am the culmination of my past.

A time traveler.

Yes! You are Who, Dr Who.

The past has gone for good and the future I am pretty sure I am gone soon. So if you ask who I am, I haven't found out yet.

MInd. Blown.
