Anton Helios<p>I drove to my office at 560 Westmount. I had a small office in the Quantum Investments building. Many years earlier, one of my investments had eventually led to some significant returns, and a solid relationship with the founders of QI. I checked to see if Neil, one of the founders, was in. He was, and we settled into one of the meeting rooms.</p><p><a href="https://21cm.ca/tags/PositiveSF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PositiveSF</span></a> <a href="https://21cm.ca/tags/CanadianSF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CanadianSF</span></a> <a href="https://21cm.ca/tags/HoE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HoE</span></a> <a href="https://21cm.ca/tags/Transmigration" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Transmigration</span></a> <a href="https://21cm.ca/tags/MachineIntelligence" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MachineIntelligence</span></a> <a href="https://21cm.ca/tags/Robots" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Robots</span></a> <a href="https://21cm.ca/tags/Gaia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Gaia</span></a> <a href="https://21cm.ca/tags/SelfConsciousness" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SelfConsciousness</span></a></p>
