Processual archaeology continues to be used today, however it is not the same as it was when it started. The biggest change came with computers. The models that archaeologists could be tested and seen to be accurate or not. More detailed examinations of artifacts could be made. Not all archaeologists think the same way about the past. After processual archaeology came post-processual archaeology which challenged a lot of the assumptions being made. Both processualists and post processualists exist today.
