| | <p>The human brain probably stores around <a href="/doku.php?id=ai_timelines:information_storage_in_the_brain">10-100TB of data</a>. Data storage costs around $30/TB. Thus it costs roughly $300-$3000 to buy enough storage space to store all information contained by a human brain.</p> |

| | <p>If we suppose that one wants to replace the hardware every five years, this is $0.007-$0.07/hour.<span class="easy-footnote-margin-adjust" id="easy-footnote-1-592"></span><span class="easy-footnote"><a href="#easy-footnote-bottom-1-592" title="$300 to $3000 / (5 * 365 * 24)"><sup>1</sup></a></span></p> |

| | <p>For reference, we have estimated that the computing hardware and electricity required to do the computation the brain does would cost around $4,700 – $170,000/hour at present (using an estimate based on <a href="/doku.php?id=ai_timelines:brain_performance_in_teps">TEPS</a>, and assuming computers last for five years). Estimates based on computation rather than communication capabilities (like TEPS) appear to be spread between $3/hour and $1T/hour.<span class="easy-footnote-margin-adjust" id="easy-footnote-2-592"></span><span class="easy-footnote"><a href="#easy-footnote-bottom-2-592" title='&#8220;So it seems human-level hardware presently costs between $3/hour and $1T/hour. &#8221; &#8211; our blog post, <a href="http://aiimpacts.org/preliminary-prices-for-human-level-hardware/">&#8216;preliminary prices for human-level hardware&#8217;</a>.'><sup>2</sup></a></span> On the TEPS-based estimate then, the cost of replicating the brain’s information storage using existing hardware would currently be between a twenty millionth and a seventy thousandth of the cost of replicating the brain’s computation using existing hardware.</p> |
