Welcome to another T-Rex talk. This is Isaac Botkin, and this particular T-R-X talk is one of the audio-only,

podcast-only versions. This one was not a YouTube live stream. I had been planning on doing an

audio-only podcast upload every week in addition to the YouTube live stream that we do every week.

And then I also upload onto the podcast.

And I hadn't really picked a date to do that, but this seems like a pretty good week

because the very last YouTube live stream that we did was Lucas talking about weapon lights.

And it was a great live stream.

He demonstrated things very very clearly on

video but they're not very clearly demonstrated on audio so this seemed like as good a week as any to

try to add an additional audio only podcast for those of you that don't have the time or the

ability to watch youtube videos and would prefer to have an

audio-only podcast to listen to. So I am going to talk a little bit about flashlight's technology,

but also just sort of technology in general, particularly disruptive technology. So as I was

watching Lucas's live stream and moderating the ridiculous comments that always end up on the YouTube videos,

and fortunately don't seem to end up on any of the podcast, another reason that I like the podcasting side of things.

It's kind of amazing to me, just how far the technology of flashlights has come over the years.

I'm pretty old. In fact, I'm old enough that I remember being part of the Radio Shack Battery Club.

Every month, you could go into Radio Shack. And if you were a member of the Battery Club, which was some kind of

primitive loyalty program, you would get a battery. And so I was very eager to go to Radio Shack once

and I think it batteries because flashlights, when I was little, they went through batteries

very quickly. And the little dinky incandescent bulbs that they had were not very bright.

And if you're relatively old, you will remember a time when flashlights were pale shadows of what they have now become.
