If you would want to experience another world, you wouldn't want to have your sensors/effectors too far away from your brain. And it doesn't matter if you would be flesh or silicon.
Even planets in our solar system are already too far for remote interaction.
It does matter. It is cheaper to send 100 lbs of computer+powersupply, than to send 10,000 lbs of human+lifesupport.

If you existed in silico, why would your sensors need to be far away from your effectors?
Edit: Sorry, I corrected my older comment, it was supposed to say "sensors and effectors far away from brain".
You cannot effectively "be present" [1] at the remote world if your perceive-think-act loop would be spread over large distance.
So even if you would be in silico, you would still need to transfer your actual hardware, not just dumb robots.

If, as I originally posited, humans were to evolve into in silico entities, then human beings (= naked apes) would not exist, would they (other than, perhaps, as specimens on display in zoos)?
Your somewhat glib response reminds me this:
But I should remember, Krauss said, that the long run is a very long time. He told me about a meeting he attended at the Vatican a few years back on the future of the universe: "There were about 15 people, theologians, a few cosmologists, some biologists. The idea was to find common ground, but after three days it was clear that we had nothing to say to one another. When theologians talk about the 'long term,' raising questions about resurrection and such, they're really thinking about the short term. We weren't even on the same plane. When you talk about 10^50 years, the theologians' eyes glaze over.
