Sure but that means a workaround for machines affected, but not needing correct dates could be to set their clocks to midnight Jan 1 1970 and have another 65 years to sort it out

Anyway, the biggest problem will be embedded systems, including many household and business smart devices. Several I have are definitely 32 bit machines and might use 32 bit time precise to the second. Some I don’t know. I have no idea what processor my TV uses

And as long as they get updated, it’ll be fine. Probably cheaper than Y2K. Note that medical and industrial control stuff generally doesn’t care about the date
