I think this is almost certainly wrong for two reasons.
1) It would be wonderful if "want" will disappear in the future when information technology, or technology in general, will have advanced in ways we can't imagine. But we are physically limited to whatever resources we have on the planet, and maybe a few close asteroids. Right now, even clean water, clean air, and food aren't as available as we would like everywhere on the planet, and it doesn't look like we can assume that will get better as the population continues to grow.
2) Even if we had unlimited energy and maybe a Star Trek replicator to create any kind of matter we need, wouldn't that tend to make a species more curious about the rest of the universe? Humans who are barely surviving don't wonder much about other planets when they're wondering where the next meal will come from. But humans (and maybe also aliens) who have most of their wants already answered would be much more likely to look farther afield for challenges.
In short, I believe in more of a Star Trek/Star Wars future than a Wall-E future.
