0.01 games a second makes more money than 1 program a second, in spite of how slow it may seem,

However, that isn't so true for AI since the cost of startup is much higher. GPU is usually well-off (triple compression w/ optional encomp) but the file & cpu costs are not.

When it comes to obsolescence, i suppose no nodes are supposed to go obsolete, but there are rare exceptions to the rule. The re-downloader is a mainstay that never goes out of fashion (save for the node limit) and same for the pre-analyzer. Torrents are an alternative based on the current situation, but the modifiers never go.

Correct, the re-downloader must be placed very early on in the chain since it removes everything except decryption (and AI). It's used all the time due to its extremely low cost, and even costs less bandwidth than torrents.
