Several years ago, I did the side by side experiment of expressing the same non-trivial digital circuit (a four digit stopwatch with a multiplexed display) as both a schematic diagram, and as text with Verilog. The graphic (schematic) version was much more time consuming, and *much* harder to modify than the text-based Verilog. It became very clear why digital circuit designers abandoned graphics and switched text for complex designs.
Rep. Lofgren asked me to brief her and a few Representatives on the NSA. She said that the NSA wasn't forthcoming about their activities, and they wanted me — as someone with access to the Snowden documents — to explain to them what the NSA was doing. Of course I'm not going to give details on the meeting, except to say that it was candid and interesting. And that it's extremely freaky that Congress has such a difficult time getting information out of the NSA that they have to ask me. I really want oversight to work better in this country.
Ironic: Even though the contents of top-secret, unpublished documents was discussed, the meeting was held in a regular conference room, because Bruce didn't have the necessary security clearance to enter a secure government facility."
