Do we still need to release 32-bit versions of our software?

It is now 2015 - do we still need to release 32-bit versions of our software? Most people (to my knowledge) are running 64-bit operating systems, and you would probably have a hard time finding a store that sells a new computer with a 32-bit architecture. Despite all of this, people still release 32-bit and 64-bit applications, and even publish the 32-bit version as the default. What gives? I have half a mind to only release a 64-bit version of my software, and if anyone can't run it because they only have a 32-bit OS or processor, let that be a suggestion to them that it's time to get a 64-bit machine.

Now, tell me why I'm wrong.

Yes, there are still several benefits of 32bit that 64bit doesn't have. Have a read:

Because there are a lot of people who still have 32 bit computers which run fine and therefore don't need to be replaced at the expense of the user.
