They're talking about Apple supporting Intel processors, not shipping them. An Intel MacBook Pro bought in 2020 is not going to be obsolete for many, many years - partly due to perhaps one or two more MacOS versions being released for it.Actually, this is not correct. Apple is on course to eliminate Intel as it did PPC. so, within the next 3 years or less Intel will be history. Sorry, but your statement shows no merit without any sources.
And it's silicon. Silicone is a synthetic material used in caulks, oven mitts, and fake boobs. FYI.
