impossible fifty years before, the linkage between brains and ship were made more efficient and sensitive and almost foolproof. The cold-sleep systems were improved.â
âI have divided feelings about it,â said Horton. âHowever, I guess it personally makes no difference to me. If you canât live out your life in your own time, I suppose it becomes immaterial when you do live it out. What I do regret is that I am left alone. Helen and I had something going for us, and I liked the other two. I suppose, as well, there is some guilt because they died and I lived on. You say you saved my life because I was in cubicle number one. If Iâd not been in it, one of the others would have lived and I would now be dead.â
âYou must feel no guilt,â Nicodemus told him. âIf there is anyone who should feel the guilt, I am the one, but I feel no guilt, for reason tells me I was capable and performed to the limit of current technology. But youâyou had no part in it. You did nothing; you shared in no decision.â
âYes, I know. But, even so, I canât avoid thinking â¦â
âEat your soup,â said Nicodemus. âThe roast is growing cold.â
Horton had a spoonful of the soup. âIt is good,â he said.
âOf course it is. I told you I can be an accomplished chef.â
âCan be,â said Horton. âThatâs a strange way of putting it. You either are a chef, or you arenât. But you say you can be one. That was what you said about being an engineer. Not that you were one, but that you could be one. It seems to me, my friend, you can be too many things. A moment ago you implied that you were, as well, a good cold-sleep technician.â
âBut the way I say it is precisely right,â protested Nicodemus. âThat is the way it is. I am a chef right now and can be an engineer or a mathematician or astronomer or geologist â¦â
âThereâs no need for you to be a geologist. Iâm the geologist of this expedition. Helen was the biologist and chemist.â
âSome day,â said Nicodemus, âthere might be need of two geologists.â
âThis is ridiculous,â said Horton. âNo man or no robot could be as many things as you say you are or could be. It would take years of study, and in the process of learning each new specialty or discipline, youâd lose some of the previous training you had taken. Furthermore, youâre simply a service robot, not specialized at all. Letâs face it, your brain capacity is small, and your reaction system is comparatively insensitive. Ship said that you were chosen deliberately because of your simplicityâbecause there was very little that could go wrong with you.â
âWhich is all true enough,â Nicodemus admitted. âI am what you say I am. A runner-of-errands and a fetcher-of-objects and good for little else. My brain capacity is small. But when you have two brains or three â¦â
Horton threw down his spoon on the table. âYou are mad!â he said. âNo one has two brains.â
âI have,â said Nicodemus calmly. âI have two brains right nowâthe old standard, stupid robot brain and a chef-brain and if I wanted, I could add another brain, although I do not know what kind of brain would supplement a chef-brain. A nutritionist-brain, perhaps, although the kit doesnât have that kind of brain.â
With an effort, Horton controlled himself. âNow letâs start over,â he said. âLetâs take it from the top and go slow and easy so that this stupid human brain of mine can follow what youâre saying.â
âIt was those fifty years,â said Nicodemus.
âWhat fifty years, goddammit?â
âThose fifty years they took after you were frozen. A lot of good research and development can be done in fifty years if a lot of humans put their minds to it. You trained,
