"China wants to take over Taiwan's semiconductor industry!"

What China wants is irrelevant to what it can have. The foundries on Taiwan are pre-wired for explosive deconstruction, and that detonation is only controlled externally to Taiwan, and will be initiated in the event those foundries are possessed by the CCP, whether willingly delivered or taken by force.

"I guess China would try to conquer Taiwan because they don't have a carrier battle group to support Iran!"

I believe that China does have a carrier battle group, but also that carrier battle groups are today obsolete. This has been proved by the Houthis, whom have caused $T carrier battle groups to withdraw from the Red Sea with FPV drones made of sticks and string, because all they must do to render the carrier incapable of projecting force is dimple the flight deck so that planes cannot launch or land on it.

Today the evolution of technology has caused decentralization of means of production of, particularly, military arms that create security, to be the cutting edge of technological advance. $T weapons systems are inferior to $15 drones that can drop $50 grenades. It is these facts that have caused me to reconsider how China might best secure the supplies of oil it's existence depends on, from taking Taiwan to directly confronting the cultists attacking Iran and the gulf states today. Because China can quickly produce vast swarms of drones that can quickly bleed off their defenses and easily render carriers incapable of projecting force, I believe that is the most effective option on the table for China.

The same is true for all of us today.
