Your argument is "it hasn't happened yet, therefore it cannot happen". This argument proves entirely too much; it implies no technological change can ever occur. To make this argument, you have to demonstrate that the situations in which the change did not occur are the same in all important respects as the current situation. And you cannot do that. Here's what's different.
(1) The cost of renewables has crashed, especially in the last decade. In the case of PV, by nearly an order of magnitude. This is an extreme rate of change for an energy technology.
(2) The cost of storage has also fallen rapidly, and continues to fall.
(3) Market conditions are now beginning to favor installation of storage, as they didn't before (when there's enough dispatchable gas on the grid vs. renewables storage doesn't pay off.)
(4) The existing infrastructure was largely installed at times when renewables were not competitive. However, it won't be ripped out until it becomes uneconomical to operate it (which means ignoring its capital cost). So observing that the source are still being used doesn't imply renewables are not winning.
(5) Fossil fuels have not, and still large are not, being taxed at a level appropriate for the damage they are going to do. Renewables don't have to beat fossil fuels unburdened by CO2 taxes (although we may have waited long enough with CO2 taxes that they may increasingly do so, at least in some market conditions). CO2 taxes will rise to the level needed to push fossil fuels entirely out of the market, and then the question becomes "which is cheaper, nuclear or renewables (or, possibly, fossil fuels with CCS)"?
(6) Once fossil fuels are out of the way, it is crystal clear from the data that absent some technological breakthroughs, new nuclear power plants are grossly uncompetitive vs. renewables. This (and not ludicrous conspiracy theory) is why you're seeing massive installation of renewables around the world, and nuclear installs are gasping for breath.
