I too worked in the computer field back in the 80's. In fact I worked for the company who's visionary founder Ken Olson made the statement "no one will ever want a computer in their home". Needless to say that belief led to the destruction of the company. I also saw many of my co-workers financially wiped out at the market crash of 1987.
I have been working hard to learn about cryptos & the blockchain. I have far more faith in this technology than in the PPT controlled stock market. Too bad I lost my PM's in that boating accident :-(
