Build vs BuildX

I'm using Build to build docker image. I keep getting this message that build is deprecated and I should use buildX I understand that buildX allows the creation of images depending on the architecture if the host os. What I don't understand is what problems was buildX aimed to solve. Also should I be worried if the other person using the docker compose file is using build or buildX. Any information about it is helpful. I tried searching the docs and asking chatgpt but the answer were very limited just saying that buildX is better and faster
