I wouldn't go that far.

While everything is slowly moving to 64, there are still loads of software and such that haven't made the jump-up to 64 bit yet.

If the 32 bit system in question still retains any speed or still has decent memory or anything, it definitely hasn't seen the end of its usefullness yet.

From an assembly language point-of-view, everything should be backwards compatible. However, that isn't always the reality. So even though a 64-bit program will not run on a 32-bit program, you shouldn't have issues running a 32-bit program if you have 32-bit emulator.

Windows

For Windows, this is mostly achieved via the WOW64 emulator service that is built into Windows. However, if you're trying to run some Windows programs that were before Windows XP Service Pack 2, you may run into issues involving the kernel security lockdown. In that case, you may need to virtualize an older Windows operating system. You can download images of legacy Windows operating systems from Microsoft's website - and don't download them anywhere else since those are illegal and will likely have malware/viruses. After you run those program images, you'll need to enter your Windows key for that specific operating system.

Other Main Operating Systems

For Linux and MacOS... it gets a little more complicated. Many UNIX and other proprietary operating systems, many of those will remain 32-bit with a few 64-bit variants.

Special Cases

With the emergence of Internet of Things (IoT) or 5th Generation technology, there is a benefit of having systems with less capacity and less demand on utilities (energy, etc.). So 32-bit systems will likely remain in embedded OSes for the long term. Of course, you'll need to keep in mind that there is a 4 GB memory limit for 32-bit OSes.

The same can be said about other modern technologies, like for example IP version 6. There will likely be IP version 4 backwards compatibility for systems for the next 100 years - if God wills that we remain that long.
