Exactly - and if you were to plot the resistance (between you and the wire)
over time as you made the connection, you'll probably find the
transistor-based current limiting circuit can reduce the voltage faster than
you can touch the wire...

All the material I've read states a level of current that is dangerous, not
power. The "power" would vary depending on how good your connection to
ground was.
As for very short pulses of dangerous current, I don't know what the outcome
would be, and don't want to try it!
