Clarification: tech as in tech for this computational generation (i.e. Smartphones). Pretty much everything there has been done, and it won't be until new platforms that exist (like drones and VR like you mentioned) that interesting things will be made.

That being said, such shifts do not often treat incumbents well. Microsoft dominated the PC market in the 90s and early 00s, but their smartphone/tablet is barely a footnote in the market.
