Alexandra Freeman [0] or Lionel Tarassenko [1] might fit your criteria as technocratic appointments to the peerage - just how "like" TBL do they have to be? Sir Timothy seems like the kind of character who could reasonably be appointed, too, if that's what he really wanted.
I agree with your point that it's dominated by businessmen and aristocrats, but maybe not quite as badly as you think.
Freeman, has spent most of her career as a science in science communication (director and producer of BBC documentaries, then a "communications" role at Cambridge).
I like TBL as an example partly because of his interest in the broader consequences of technology, and the contrast with people who have made money from the technology her inventented being peers.
