Remember this your life. So go with your instincts and trust yourself. This is only a set of general thoughts to consider. Your situation is unique to you.
GT is world class USC is world class.
Masschusetts is world class in informatics and ai. It’s a flagship state university with a different mandate than tech or a private like USC.
So not every student is at the same high school caliber as you at UMass. That does change once you arrive, generally, and as you advance in your major. By junior year all your classmates will be smart.
So as an entrepreneur you will also learn about the concept of “trade offs”. very quickly or fail. It’s not black or white. There are shades of gray in decision making. Is the absolute best car in the world better than the cheapest. Not really if your only concern is getting from place a to b. Or you can’t afford $100,000. And the schools you are looking at are not that vast a difference.
If money were not an issue. I would say go to usc and be one of the best students and get into the tech vibe out there.
GT is great. As an entrepreneurial focused CS student, my concern would be that the supremely talented stem high schooler, will be one of the crowd in CS at GT. You will spend more time keeping up in those areas than expanding into some others that may interest you. If you want to be an engineer or designer, I would reverse my thoughts. GT is powerful brand in those circles. Especially working for established, big name companies.
My personal experience in the tech start up space, is no one cares where you went to school once you are at a certain level of quality.
It’s more about what you can do. How creative and driven are you.
And who your friends happen to be early on in your career.
That’s a real advantage of some schools. MIT Stanford Harvard etc. USC is in that category too. GT is just super highly regarded.
If you choose one of the two powerhouse schools at least you will have considered all of your options. And when you go to hire someone for your start up, make sure you give the UMass kid a fair shake!
