Those who think their livelihood depends on sticking their head in the sand and hoping everyone else will do the same are sorely mistaken.
The truth of the matter is that there's plenty of time for the shift. Several in the industry will simply retire. Those just coming into the industry/having recently entered the industry should already be aware of EV's. If they aren't, they haven't done their homework regarding their career path choice. Regardless, they'll be young enough to change that path.
The people that will be most affected are those that have been in the industry for a significant amount of time, are of an age that doesn't allow them to easily switch fields but also not yet positioned for retirement. Fortunately, ICE's will be around for a very long time and there will need to be people to fix the 'classics'. Swapping out 2B ICEs is going to take time. Anyone 'caught' in the industry without a plan during this transition, ultimately deserves what they get for not keeping up with what's coming down the pipeline in their industry and preparing thusly.
