Question

Why do new scientific discoveries or technological developments often lead to new career opportunities?

Answer 1

Let's look at it through the pokemon world, // I'll use a commonly known pokemon, Machop !
Machop goes through three evolutionary phases, machop -> machoke -> machamp.

which if you are unfamiliar with pokemon in general, this means that the Machop gets entitled to learn better moves, the pokemons stats might go up a little ( strength, agility, etc. ) and their bodys will change. ( also entitled for other things in the games )

For instance, machop and machamp only have two arms but when you get to the final evolution he/she turns into machamp and then has four hands!!! cool right?
So thats the best of the best for the machop family!! Keep leveling up the pokemon and you'll do great at battles, and pageants nn more!

lol so what i'm trying to show here is that, with the upgrades ( evolution ) we get more chances to be at our very best and keep achieving. But you need people to continue studying and keep our technologies up to date, thus you give people jobs for that.

sorry if you didn't get any of this lol
