Welcome to the world you will be taking jobs in and where you will begin building careers, and at times shaping history.

It isn’t the world of your parents, and it isn’t the world your college has taught you about, because it is changing too fast. It begins anew daily. As Maya Angelou said, “This is a wonderful day. I haven’t seen this one before.”

There are three big forces looming on the horizon that will shape your world and that you will play a role in shaping. They are technology, specifically AI; politics, the harsher politics of today; and the environment, which is eventually everything.

AI will have an effect that defies comprehension — it is so enormous. It is also evolving so fast that it keeps slipping out of your grasp.

“It is exponential, and human thinking is linear.” So said one of the foremost thinkers about AI, Omar Hatamleh, former head of AI at the NASA Goddard Space Flight Center. He has written five books on AI.

All that is absolutely, definitely and incontrovertibly known is that AI will affect everything. It will change how we work, play and learn. It will change how we mate, think and expect.

Graduates, you will come to realize that political action and speech have changed from what they were. Both are out of the guide rails that have served them well over time.

Authoritarianism has taken root in America, and it will be hard to pull out. The bureaucracy has been politicized. There has been an expansion of presidential power over areas constitutionally assigned to Congress, under the watch of an accommodating Supreme Court.

There are troops on American streets, political searches and seizures, arrests and indictments, and deportations without due process. All this was unleashed with the Republicans. When Democrats take power, will they put the evil genie of unconstitutional government back in its bottle?

Domestic politics has also changed our relations to the world — a world where America, Canada and Europe stood together, sharing a common heritage and a common view of law, and savoring a shared peace in Europe until Russian President Vladimir Putin invaded Ukraine, and set in motion four years of bloody fighting.

Could we have done more? Yes, more weapons, more money, and less acceptance of Putin. Maybe troops, too.

We didn’t, and that has changed the world. Free countries now know that America won’t axiomatically have their backs. That time is past and will have major geopolitical consequences.

Internationally, the big, open American hand has been closing as it has curtailed or ended participation in international institutions from NATO to the World Health Organization to the Paris climate agreement. The arbitrary closing of USAID was a declaration of withdrawal from the world and from the exercise of soft power as a diplomatic tool.

Another challenge for future Americans as they grow into adulthood: They will live in a more dangerous world with fewer friends. Hubris is an expensive luxury.

They may also not live in a world where the climate is as predictable as it once was. Already aberrant, unpredictable weather is the norm with hurricanes, tornadoes, floods and tinder-dry regions.

Politicians may deny that the climate is changing, but the evidence is there. Sea levels are rising, city streets are flooding, and beachfront homes are being swept away. Hurricanes and tornadoes, part of our usual weather cycle, are getting more severe. Drought and floods, recurring phenomena, are worsening.

Texas and the Southwest, which have long attracted working and retired residents, are facing prolonged droughts and water shortages that will curb future growth.

Dealing with the environment is a challenge that AI may meet quite dramatically. Its ability to predict, organize and find the exit in dense data is without peer.

Graduates, as the generation coming of age in 2026, you shouldn’t fear AI; rather, you should throw yourselves at it and learn what it can do for you. Gradually, it will be understood, regulated and you will come to terms with it as a tool, not an aggressor.

We have left you a messy world, but it was always that way.

Over two and a half centuries, America has absorbed and changed. Along the way — including civil war — it produced a society in which there is still opportunity; there is still freedom, although the door may be closing; and much has been perfected here.

Remember, more people live better in the world today because of America, its ideas, its inventions and its heart. Go forth and be that American.
