From a practical perspective, technology that allows for a larger carrying capacity of humans on the planet would make it possible for more people to live in the world, but there would still be a carrying capacity. Unfortunately, there will always be a carrying capacity, and a finite number of people that can live off of the resources we have. Since overcrowding and population growth is a topical issue, such technology would be favorable to have, but it could be very expensive. Depending on the cost, it could be beneficial, but research might be better placed elsewhere.
