Extraordinary work. We’re able to go back to the dates and times when our labs were operational. This context is profound for our engagement with schools around the world. Well done!

All transformative inventions and innovations seems to come from similar scenarios like "I was playing around with these things" or "I just met X at lunch and we discussed ...".
I'm wondering how big impact work from home will really have on humanity in general, when so many of our life changing discoveries comes from the odd chance of two specific people happening to be in the same place at some moment in time.
Perhaps this is why we see AI devotees congregate in places like SF - increased probability

I'm not sure the comparison is apples to apples, but this article claims the current AI investment boom pales compared to the railroad investment boom in the 19th century.

> Next, Kedrosky bestows a 2x multiplier to this imputed AI CapEx level, which equates to a $624 billion positive impact on the US GDP. Based on an estimated US GDP figure of $30 trillion, AI CapEx is expected to amount to 2.08 percent of the US GDP!
Do note that peak spending on rail roads eventually amounted to ~20 percent of the US GDP in the 19th century. This means that the ongoing AI CapEx boom has lots of legroom to run before it reaches parity with the rail road boom of that bygone era.
Consider other infrastructure such as the US highway system. There may be an expansive bubble, but infrastructure such as the increase in base power production needs to be factored as well.
