I don't think 9/11 was simple. But by and large you're correct that they don't have the patience, organization, or funding for the most part to execute more elaborate attacks (at least on the West, one could argue ISIS was pretty damn organized in their conquests in Iraq and Syria.) They seem to prefer more immediate low-effort things like simple suicide bombings, driving into crowds, or in the UK even knife attacks. We should be grateful for their lack of vision.
I'm specifically worried that the most dangerous thing about Coivd-19 is that it woke up the world to how much damage an infectious virus can cause. Technology is now at the point where you can engineer a virus like this in many university labs with maybe a team of a dozen or so and low millions of dollars of funding. That's potentially within reach of major terrorist organizations. If you're just lashing out at the world it's tough to get more bang for your buck so to speak.
Fortunately, the circles of educated, STEM type of people and radical Islamic militant types are largely exclusionary.
