Thanks for the comment. "Spreadsheets are dead, long live spreadsheets!" does actually capture the intent of the article more accurately. But I used "..., long live reactive programming environments!" because I wanted to emphasise the point that spreadsheets are actually reactive programming environments. The article isn't try to suggest that the spreadsheet interface is going to be replaced. Rather is says that by combining it with a "code-based" approach we might be able to create a whole lot of benefits for testability, audit-ability and reproducibility.
