>computers are orders of magnitude nimbler than what experience in our day-to-day

True but that's looking at it from only a technical POV. The market clearly doesn't care about some extra latency, and in return bloat means a massive decrease in the cost and time taken to develop software. Electron allows a company to use a single team of web devs (most common skillset, cheaper labor pool) cross-platform, why would they give that up for better performance? The bloat will keep piling as long as that's the case.
