Ok, not having a soul is a bit harsh, but I will explain my reasoning with a little bit of economic theory.
In life people make sacrifices, they decide that maybe studying video game design isn't the best idea, so they decide to do something practical like computer science and mathematics. Now lets simplify this; in their working life people gain utility from there jobs in 2 ways
1. They enjoy their job
2. They enjoy the stability that their job brings through income and employment opportunities in their field
(I will refer to these as 1. and 2.)
Now, this individual would have maximized 1. by going and studying game design, but he realises that the stability and availability of jobs in the game design industry is not great, so the value of 2. will not be very high. So now this individual thinks to himself, how can I make 2. higher without decreasing 1. too much. Basically he is making a compromise between 1. and 2. and the best compromise he could make was to study computer science and maths. The weight place on 1. and 2. vary from person to person, those kids that study music value 1. far higher than someone that studies finance.
Now what im saying is, that someone that decides to study actuarial puts 100% of the weight on 2. and 0% on 1.
They literally do not care about any sense of satisfaction or enjoyment in their job, and I find that very robotic and soulless. If you look at Maslow's hierarchy of needs you will see that they have essentially ignored the top half of the pyramid, which is everything that makes us human.
Now I'm sure that someone will argue that they "love" actuarial studies, and of course you would tell yourself that. If you are neglecting 1., it is your best interest to try and convince yourself you gain great satisfaction from your studies/profession.
Of course I just made this all up, but this was my thought process in calling it soulless.
