It's very hard to conceptualize where technology will be in another 100 years, impossible to conceptualize where it will be in a million years. If we are contacted by aliens, it's pretty likely their civilization is on the scale of being millions to billions of years older than our own. We can't even begin to guess what their limitations are.
