Once upon a time I took great care to ensure that TEX82 would be truly archival so that results obtainable today would produce the same output 50 years from now but that was manifestly foolish. Let’s face it, who is going to care one whit for what I do today after even 5 years have elapsed, let alone 50. Life is too short to re-read anything anymore in the internet age.

Nothing over 30 months old is trustworthy or interesting.
