I need money to survive. Just by doing research on my own I won't get paid. Doing Phd helps because most of the time one gets to work on interesting stuff and get paid by grants. Work at a good place like IBM ( and any other company which provides research based work ) would help me achieve both ( money and good work ). I can try and do routine software work for some company and carry out interesting projects in free time but it will have some limitations. At this stage of my life I cannot sit and do just research. I need someone to pay me for my living.
