what came first the video card or the algorithm?

did people make these algorithm to run on the video cards, or where the algorithm always there and the video cards just ran the numbers?

BTC was developed by Satoshi as a CPU minable coin with the principle of 'one CPU, one vote'. It remained a CPU only coin for the first few years until eventually it had gained enough notoriety and profitability for people to look in to developing a GPU miner for it and eventually, ASIC miners. Even today there are some new POW algorithms that are launched as CPU only, until a GPU miner is developed.

so he based it off the cpu code. I wonder how satoshi feels about master nodes

Satoshi was a big proponent of decentralization and equal access, hence the 'one CPU, one vote' philosophy for reaching consensus. The way masternodes have evolved in to goverance by those with enough coins to hold a masternode is contrary to his original vision, IMO. Likewise I don't think Satoshi would approve of the current centralization of mining in BTC.
