Highly recommend this read. Very interesting and well written.

If you liked this and you want to go old school for a bit, check out these virtual sliderules. Do a few calculations. Its very addicting.

Extremely well written. Hoever i think the ending does not focus on something very important. there are many ideas that are ahead of their time so do not work out very well.
