The scripting language in Bitcoin is important because it is what makes Bitcoin 'programmable money'. Within each Bitcoin transaction is the ability to write a little program.

Ethereum has taken what was a four-function calculator of a programming language in Bitcoin and turned it into a full-fledged computer.

When the actual Bitcoin network launched in 2009, no one knew about it, and many of those who did thought it would surely fail. Just to make sure the thing worked, the scripting language in Bitcoin was intentionally extremely restrictive.

Bitcoin's value is the same: It will remain as long as it is the most efficient mechanism for transferring ownership.

Bitcoin is valuable as a currency because of the economic efficiencies the bitcoin network is already creating as transactions flow over it. As with the Internet, more applications will flourish which will make the bitcoin network, and thus bitcoin as a currency, valuable.

Just as the Internet brought the cost of disseminating information down by an order of magnitude, bitcoin brings the cost of transferring ownership down by an order of magnitude.
