<p>> How would the government even be able to determine if a business increased product prices due to tariffs vs other factors, or even if the business increased prices at all? What if the product is a loss leader and the company was fine just eating the expense? Or what about a nefarious company who manufacturers their stuff in Canada but used "tariffs" as an excuse to increase prices? What would they be refunded from?<p>Gee, I don't know, receipts ?<p>Also simply revenue on the business end</p>

<p>I guess it depends on where you went.  I was a CS student at Virginia Tech in the late 90s.  The CS department wasn't even in the engineering school.  We did have to take computer architechture which was the only courses other than math/physics we had in common with EE/CE<p>I know at MIT it was (and I think still is) one major - EECS, and students had substantial latitude on how much they wanted to concentrate into hardware or software at least after the intro courses.</p>

<p>Can't find the reference but from an interview with his parents there apparently there wasn't much "nurturing" other than simply making available the necessary materials which he gobbled up.  Its not like they put a made him practice for an hour a day.<p>A boy in my high school class made IMO and got a gold medal (and later on won the Putnam one year).  They interviewed his parents and it was a similar story.</p>

<p>> Renewable energy technology is ready, right now today, to replace fossil fuels. All we have to do is start doing it, but the Oil lobby is just too strong apparently. There is no political will. I wish I was wrong, but I just don't see humanity pulling together to solve this one.<p>Sorry, but its really not.  Perhaps in some sectors such as ground transportation, but definitely not in air and sea transport and fertilizer production, and many industrial processes. At least not at scale, where would have to make massive lifestyle sacrifices which are not politically acceptable outside of extreme authoritarian states who have no reason to do this anyway.</p>

<p>Its a case of prisoner's dilemma.  Individuals making the proposed lifestyle changes in order to make a genuine dent in AGW amount to jumping on the tracks in order to stop a freight train.<p>This is the one issue where I feel some sympathy with the right. I hate "Virtue signaling" about as much as they do.  I'm sorry, but if you are going to snap at people over eating beef, while you fly/drive all over the country/world unnecessarily, you are absolute full of shyte.</p>

<p>> ethereum has a similar ewaste problem<p>Is it any worse now than say, the NYSE ?<p>This reference says energy usage was 0.0026 TWh (2.6 GWh, or 2600 MWh) in a year<p><a href="https://ethereum.org/energy-consumption" rel="nofollow">https://ethereum.org/energy-consumption</a><p>If the power was used over the whole year (and not just one hour)<p>(2600 MWh / year) / (24 * 365 h/year) = 0.29 MWh = 296 kWh.  Thats like hair dryer levels of power consumption (if the hair dryver was left on all the time)</p>

<p>> Finally, if we limited ourselves to earth-based raw materials, we would eventually reach a point where the remaining mass of the earth would have less gravitational effect on the satellite fleet than the fleet itself, which would have deleterious effects on the satellite fleet.<p>The Earth's crust has an average thickness of about 15-20 km.  
Practically we can only get at maybe the top 1-2 km, as drill bits start to fail the deeper you go.<p>The Earth's radius is 6,371 km.<p>So even if we could somehow dug up entire crust we can get to and flung it into orbit, that would barely be noticeable to anything in orbit.</p>
