Desktop applications as a means of using computers for the general public are long dead, and the test is simple, try to name a few desktop applications that are new in the last 5 or even 10 years, compare it to the number of applications mobile and / or web applications. Also look at how many end users renew their desktop / laptop often, this has been a downward trend for the past decade, major desktop companies shifted their focus to the professional audience as the general public gets 90% of your computing through your phones or the browsers on your 5-year-old laptops, because unless you're a hardcore gamer, you won't update your hardware every two years like you used to.
