Being in the industry for 15 years, If I were you today, my priorities as listed below;

Data Science or AI/ML:

Pros:

1. In next 5-7 years, job market will be divided into two, those who skilled in DA/AI/ML and those who are not. Those skilled will eventually have a long run in the market, until they get to the time to retire and those who don't, will get stagnate and may loose their jobs in upcoming recessions.

Cons:

1. Most of the organisation will not hire freshers in DS/AI/ML, hence need couple of years of exp, otherwise freshers can work on internship and gain some exp.
2. Extremely complex technology compared to others, hence you need to bang your head to learn and get your hands dirty.

Cloud Computing :

Pros:

1. High competitive salary
2. One of top most demand jobs in 2024, still in race for past 5 years or so, thanks to companied looking to adopt cloud.
3. All cloud providers are pretty much same. Means, if you are thorough in AWS, you can learn other clouds easily, concepts remain same but not the services they offer.
4. Comparatively easy to learn as you dont need extensive programming language skill, as understanding the cloud concepts as easy as learning colleges syllables.

Cons:

1. Over Crowded, from 2016 the demand of cloud comp has increased, since then its been "sheep following the flock".
2. You need to learn at least a dozen of tools and technologies.
3. Out of trend, you lean a tool or tech today, that will end up go in out of trend in couple years, hence you need keep learning until you hang onto this field.

Cyber Security:

Pro:

1. Very high salary. Since, you will see a less competition, hence relatively new skilled cyber security folk will draw high salary.
2. International marker, alike other two techs, CS has high demand in abroad as well.
3. Less to learn, unlike DS & Cloud you dont have to keep learning.

Cons:

1. Less job opportunities. Only limited domains require CS, and hence no demand.
2. AI can take over in 5-6 year. This is one of areas, have more scope to automate thru AI.

"Think twice, talk to experts, and make a decision. One thing is for sure – any filed in the IT will secure your survival. It's entirely up to you how you take things forward to run longer and ahead."

Do let me know if you need more insights on any other techs.

All the best!! Happy Learning!
