What is a tech company?
"electric vehicles represent a tantalising opportunity for any tech firm looking to diversify"
Do they? Surely it depends entirely on what exactly you think a "tech" firm actually is. As far as I can tell, it's a completely meaningless term used to describe any company that has at least one computer somewhere in an office. Online shopping, logistics, real estate rental, cloud computing, software, hardware, taxi services, telecoms, game development, car manufacturing, communications... every single one and many more all get lumped together as "tech" as if they actually have anything in common. Electric cars may well be an interesting direction for some companies to diversify, but that's only going to be the ones that already have related interests or some obvious way to gain from doing so, and certainly the word "any" has no business being involved considering the huge variety of completely unrelated industries that get lumped under the term.
