On first glance this looks kinda shady for a pirate site to borrow visitors' CPU power to mine crypto-currency. Then you realize that the revenue model for almost the entire internet is based on ad revenue, and crypto-currency mining with visitor CPU power could potentially change everything.
I spent 5 hours helping a roommate assemble an IKEA bed last night. I hated the manual labor waste of my time, but I do love the affordability and shipping convenience of IKEA. If autonomous electric vehicles become more affordable and faster to assemble than an IKEA bed, sign me up for that future!
