Valuable
The usual gold and oil are obviously valuable, but have you ever asked yourself why? I predict that gold is valuable because it is often used in many computer parts and also used in many electrical applications as it is a great conductor and very easy to mold. Fossil Fuel is a huge value as it is very scarce and the entire world depends on it for fuel. It is a great idea to have some play in this industry because as fossil fuels become harder to achieve, the value of existing fuels will rise.
Non-valuable
Maybe this makes no sense or you simply don't agree, just hear me out. Imagine having the only water bottle in the entire 1000 people filled room whose doors are locked for 7 days. Your one water bottle is the only source for water. Scarcity. Now, however, someone walks in and gives every single person from the group of 1000 an entire water bottle and a machine that pulls humidity out of the air and makes water to drink, but you are all still locked inside the room. Ask yourself how valuable water is now? If you have the ability to create energy and you can make more energy than the world needs, your energy is quite invaluable. If everyone can efficiently generate their own energy from the sun, then the "grid" becomes obsolete.
Valuable
Having the ability to automate in this day and age is a huge value proposition. This is a very valuable thing because your one employment can save a factory 10 jobs if you can automate assembly. Your technical skill to automate transportation can help a company alleviate their driver costs. Having the ability to automate anything in the corporate world and save a company multiple jobs is so valuable. I would suggest learning how to code as a side hobby just to increase your value.
This is one that is backed by billionaires such as Mark Cuban. As we can create programs that can replace the need for basic entry level programmers, we will require people who can read the data in new and different ways. Having the ability to think outside the box in huge in data analysis and if you can find a pattern in marketing data that other technical employees could not, you become more valuable.
Non-Valuable
Fortunately, we are a species constantly innovating and increasing our niche. The problem with this is that we have found ways to remove millions of factory workers with robots or cubicle workers with software. It is not hard for us to create small products and provide simple services with AI and Robots. Take self-driving cars for example. This, however, is not a bad thing, in fact, this is a great thing. We now can involve all our human efforts on serious prospects such as space exploration and knowledge expansion. We can grow bigger and greater than ever before with this technology, but we need to get all people with little experience with these mental and technical skills into colleges and into private companies trying to solve these problems.
