All for useful or interesting technology, yes.

Wall Street financial world tech, not so much... Betting against the recovery of Greece during the financial crisis, speculating on the price of essentials such as grain and water, algorithmic trading giving the advantage to huge firms such as Renaissance technologies at the expense of the small guy... not something i get excited about.

No need to pay commission to a finance guy, just get an etf if you want to join the trading game. Chances are you'll do financially better anyhow over 10 years.
