I mean using good algorithms, you can compute pi(x) very quickly even
for quite large x.  I remember trying pi(1 billion) with Mathematica on
a PC many years ago and being surprised to get the answer right away.  I
just put "number of primes less than 100 billion" into Wolfram Alpha
online and got back 4118054813 in a few seconds, most of which was
probably network stuff, English parsing, etc.  But it won't do 1 trillion.
