i'm having second thoughts about this whole "time travel" thing

I mean, seriously. When we think of time travel, we think of being physically transported to a time in the future or past. The only problem with this is that it is all up in the grill of the First Law of Thermodynamics.

Neither matter, nor its energy equivalent, can be created or destroyed, tru dat? Word. This means that the molecules of which our bodies are currently constructed will, in a few thousand years, occupy the structure of a coffee mug or iPod. Of course they will still have iPods in a few thousand years. And I will still have my old school scroll wheel, circa 2003, because I liked Apple way before all of you posers.

Anyway - so if in 1,499 years, the molecules of your body are busy inside of an Ikea futon, your body can't travel forward to that year, because this would require those very molecules to exist in a duality within singular time.

And that's just messed up. So you there, building the time machine - you should not do that. I will not get in your time machine.
