What impact? If Bill Gates had never been born, Moore's law would still have been in effect and computers would still have got ever cheaper. The Apple Mac would still have been built; the IBM PC would still have been built -- but probably running CP/M-86, DR-DOS and (later) GEM. The Atari ST and Commodore Amiga would still have happened. Unix and C would still have been invented, and their intrinsic wourth would have let to them becoming popular. HTML and http (or something very like them) would still have been invented.
The only difference is that their would have been no baleful, anti-competitive Microsoft watching over all and limiting progress. (How many startups weren't started in the 1990s because their putative founders thought Microsoft would strangle them if they showed signs of success?). So, minus Gates, if anything today's technology would have arrived quicker.
