The average life expectancy today is around 75 years. One hundred years from now most of us would be in our 120s and up so it is a bit of a stretch to assume that our life expectancy will nearly double in the next fifty years or so to make seeing 2101 possible. I'm not saying that it can't happen, it just seems unlikely that it will for now.
Most of the life expectancy gains up to this point have involved a reduction of the death rate during early childhood and also middle age. In other words, fewer babies die today than in past decades, and by the same token people who make it into their fifties or so are more likely to survive to be senior citizens. What has not changed that much is the outer limit of life. There seems to be a maximum human lifespan of about 110, with very few people making it past 100 or so.
