They are other important uses hydrocarbons other than energy production. So calling them obsolete seems a bit of a stretch.
For example take coal one of the dirtiest fossil fuels. Steel plants making carbon steel steel need to convert that coal into coke. Even an electric arc furnace needs coke to make carbon steel.
Similar things with other hydro-carbons. So its not like we are gonna stop using them even if the grid was entirely renewable and nuclear.
Now industrial processes that use such hydrocarbons to produce useful stuff other than energy are certainly a minority of the market. So mines and wells for such things will still exist. So the tech is still useful, but we just ideally stop using these hydro-carbons as fuel.
You need a little bit of carbon to make carbon steel, but the vast majority of the coke is used for heat and producing a reducing atmosphere to reduce the ore. Both of those can also be done with a process using Hydrogen.
He sort of has a point in that there are some products (plastics, etc) that are only produced from crude oil. The problem is it's pretty doubtful that fracking would be worthwhile if that was the only demand - there's more than enough normal crude to produce plastics.
As I understand it, most fracking isn't even profitable right now - it is only profitable if oil prices are relatively high.
