We started a company with the core premise that spreadsheets will never die [0]. Spreadsheets are so good at the most casual data viewing and exploring tasks to creating complex financial models. They are also the de-facto choice when you have data (not big data) from multiple sources that you need to "join". We tend to underestimate the beauty of this tool which can be used productively at all points of the skill spectrum. Everyone feels at ease in the familiar territory of a spreadsheet, which is what makes it ubiquitous and basically impossible to kill.
If spreadsheets were two-way connected with your core systems like SaaS tools, DBs, Slack, etc then you could represent serious business logic and actions without being a programmer. It is the best platform to build a "no code" tool for non-programmers.
