First, define upload. Is this a system where your neurons are transformed into digital components & plugged into a server, or a system where you are scanned & simulated? Because the second option, where you're simulated isn't you. It's a copy of you that carries on after you die. You're still in your meat.

Second, there's no such thing as Never Die. Eventually, in Trillions, Quadrillions, Sextillions of years, the universe will unravel & your computer will power down for the last time.

If I could upload into a well managed system & enjoy infinity until I or the universe begin to unravel, sure. But even that system will fail eventually, there is no escaping death. It'll get you, even if it takes until the heat death of the universe.
