Futurology

Aside from AI aspect law schools all over the world is already giving more graduates than it's needed. There is a surplus of lawyers in the world. So first you should do a research about your country and its conditions.

Secondly I don't think there will be an AI that can take over law related issues/jobs from humans (lawyers, prosecutors, judges and advocates) because that AI needs to be capable of human conciseness to understand what's going in a case. If it has achieved such capabilities than it will be sentient and we will be discussing other things than law.

To elaborate on why I think so is laws might seem like mathematical and ridgid rules but in reality trial process (which includes the judge, prosecutors, lawyers and depending on your country jury) is what decides the outcome. And laws are applied to that process and outcome according to the human's understanding and interpretation. So as a lawyer with over 20 years experience I don't think that any AI will be taking over humans in law sector unless it's a secretarial position.

Lastly in today's environment no matter what job you choose it's up to you to distinguish yourself from the rest. Because in today's environment graduation means nothing. You should focus on networking and developing yourself to become somewhat of an expert in the area of your choosing otherwise you'll be competing with the rest for the same opportunities and AI will be the least of your worries.
