Is Descartes' cogito ergo sum still valid today?

Honestrosewater ->

I think a discussion related to philosophy should be related to the arguments and ideas, and I do not believe that people that has another opinion than me, in any way, is related to worms and animals.

I think that other point of views and argumentations, that is different from mine, is valuable as far as I am able to understand it.
