Will there still be available usernames for registering on websites in 100 years

Question

Are they still going to be available usernames for websites in 100 years?

100 years from now do you think there will still be usernames available for new users to register on websites such as this one?

Answer 1

If the internet is still around 100 years from now then I'm assuming there will be usernames. Websites come and go and if websites that are still around today are still around 100 years from now then usernames will most likely somehow become available even if the old accounts aren't deleted.
