"Is something wrong with me that recently I stopped being excited about tech, products, disruptive ideas, making world better etc. And just want to make money, as much as possible, don’t care how (as long as it’s legal)."

I sort of feel the same, but would also require that I feel it is moral. I would like to make the world a better place, but I feel like most software doesn't really make an impact, and so I've disconnected this ideal from work. I hate my job and want more financial freedom.
