Arm has been designing chips that support 64 bit software for years, but the company continues to support 32-bit code.

That will change a little in a few years.

ARM announced that from 2022, all of itsBut ARM will continue to use it

So, most likely, this means that if you buy a new high-end phone, tablet or PC in 2022, and it uses the latest ARM processor, it may only run 64 bit applications.

Arm's big.LITTLE Technology allows pairing high-performance (and more power-consuming) CPU cores with low-power cores on a single chip. I suspect that if

However, some cheap mobile phones and tablets use chips that only use the little CPU core, and in this case, it seems likely that 32-bit software will continue to be supported for some time to come.

So why switch? According to arm,The 64-bit instruction set brings

Arm said it expects to deliver a 30% performance improvement over the current arm cortex-a78 CPU core by 2022, and has designed a number of schedule generation processors for its next generation and next generation, with:

Year 2021

Year 2022

Focusing on 64 bit also provides a goal for software developers, not two. Although this does bring some risks to users.

If you've been relying on old applications abandoned by developers and haven't been updated for years, they may not be able to run on devices that use updated arm chips in a few years from now. Unless you're using a cheap phone, only the little CPU core.
