At the sound of the replicator, it will be #utopia o'clock.
Low-cost matter replication is the one big thing that humanity needs to move forward. Being able to copy things as easily as we copy computer files would go a long way toward solving humanity's problems.
Not least of which being that components for our other endeavors (like AI, space travel, and fusion power) are expensive. Not so expensive any more if you can make just one and then copy it endlessly, yes?
