No. After Apple fired Jobs in 1985 the company did a continuous slide until his return but the earlier Apple Had a limited product line. Apple now has a a diverse set of products: Music, phones, computers and so forth. One might also say it was Jobs who kept the market closed for the computer lines so with him gone changes could open it up to whole new markets. And finally it was not him inventing these products, he guided the development but the engineers and designers that came up with the products are still there. Apple will be around for a long time..
