Why is it ridiculous? If you look at Transport for London as an example, the organization employs 25,000 people, of which 3,000 are train operators, with 600+ trains. The salary + indirect wage costs for those people is on the order of $250 million per year. Which I think is pretty cheap, compared to what you'd guesstimate for CAPEX and OPEX for an automated system.
Now they are actually in the process of automating the trains, which has been criticised by many as a vanity project. Certainly it has not been shown that it makes financial sense. And it has been decided that they will retain a "captain" aboard the train, for safety reasons, as someone has to lead passenger evacuation in case of an emergency. So the total salary savings will be essentially zero.
Fully level-4 automated may makes sense for new builds. But for retrofits, you can't satisfy the overall requirements without a human physically present.

The DLR has been driverless, since it was introduced in 1987 ─ it is a working example of the paradox of automation, which states: the more efficient the automated system, the more crucial the human contribution of the operators. Humans are less involved, but their involvement becomes more critical. This will be the unwritten hard limit for the time-being, when it comes to implementing the levels of autonomy, irrespective of the condition of the rolling stock or wage costs, which are moot.
No, it’s not ridiculous. It’s complex, time consuming, and expensive to retrofit fully automated systems on to existing lines. Like any other project, the costs (disruption, financial) must be balanced with the gains (capacity, safety). Automated systems will continue to be rolled out worldwide at a reasonable pace.
I think Swizec's point is that the current pace, even accounting for those factors, is not reasonable. Let's not pretend those decisions have some sort of mathematically correct answer; how much to invest in public transit, for example, is a political choice that one can legitimately disagree with - and even find unreasonable.
