There is a theory that life exists, because it is effective at spreading out energy as heat more efficently[0]. In such case, bitcoin (or having fun) can be seen as a good purpose for life. Most of activities seen by people as "fun" use up energy and spread it as heat.

This is excellent. We should found a religion based on it. CHURCH OF THE ENTROPY MOST HIGH.

Super interesting thanks for sharing.

No my point is that eventually the energy burn per transaction in crypto will likely be near zero.

Downvoting is fine but I'd take a gentleman's bet that in 10 years either crypto has <$1bln market cap or price per transaction is cheaper than credit card systems when incorporating operational costs.

Given the entire argument seems lost on readers given the downvotes it's simple: proof of stake and increased use of crypto both drive down energy cost per transaction. The more people use crypto, the cheaper energy use per transaction assuming currency prices stay the same. (This is lost on most commentators, but it's reasonable to expect price stability in the post-speculation phase of crypto adoption.) And proof of stake and side chains stand to drive those costs down by several orders of magnitude.
