I don't pay much attention to the 1763 number, for one reason:
The Congresscritters who vote on the last 800 or so of them are still serving their time in aides' offices, on school boards and in state legislatures, and the late 2020s (the buy years) are as far away from us as the year 2000, when you had to talk into a telephone, your data ran at a screaming 56 kb/sec and you could get on an airplane without being groped by high-school-dropout members of the Waffle-SS.
