By "physical world" we don't necessarily have to do some groundbreaking theoretical physics discovery. Software like online collaboration tools, marketplace apps and search engines have already greatly transformed the way people interact and work. Isn't that change "physical"? Way too many people who study "hard science" end up being able to contribute nothing and just drop out of the field, or just passing their time on pointless researches supported by funds. The field was already overpopulated and what makes it worse is that its hard problems are few to come by and solving them requires luck. If you are out of luck then you're wasting your life. This is different from the world of software where you are almost always doing things that have an immediate positive effect on the lives around you.
