. Internet was still relatively new.I mean, if your approach is "find problem, add Internet, equals solution" then yeah, you're probably going to find it a tough row to hoe these days. But I'd challenge you to broaden your thinking and be more imaginative. There's a lot more to creating solutions that "mix in some Internet".
Think about the staggering array of things you can do today, with almost no up-front investment at all, using AWS, GCE, Azure, etc., that would have cost millions 20 years ago. You can deploy a virtual super-computer running in AWS and throw it at a problem for crying out loud.
Consider too the range of awesome open-source / free software packages that are out there, and all the capabilities they enable. Consider cheap, small, embeddable single-board computers, inexpensive software-defined-radio, cheap webcams, accelerometers, gps chips, and other sensors. Consider all the Open Data that's out there already, and everything streaming in minute-by-minute (see, SDR and receiving satellite data right off the air in real-time).
Consider the 8+ billion people in the world who are mostly all potential customers given how interconnected we are with the internet and global payment systems. Look at how much easier it is now to get content in front of potential customers with Facebook, Reddit, Twitter, Google, LinkedIn, etc.
Consider that you can prototype a physical item with a cheap 3D printer, using Open Source OpenSCAD software, ship a prototype off to an injection molding outfit, sell your item on Amazon, using Amazon's warehouses and logistics infrastructure, and never touch the inventory.
Further consider how much more we know about the mechanics of starting and running a tech startup now. Ideas like "product market fit" have been formalized and are better understood, Steve Blank's Customer Development process is out there as guide, and there are tremendous resources like Startup School, etc. out there to consult.
One could go on and on and on... personally I think there's never been a better time to be an entrepreneur than right now. There is so much possibility and so much potential out there that it's staggering, IMO.
Here, try this on for size and see if maybe you can draw some inspiration from this guy (Alan Kay):

Even better, go off somewhere and lock yourself in a room with a bunch of books by Philip K. Dick, Greg Egan, William Gibson, Charles Stross, and H.P. Lovecraft - and biographies of Nikola Tesla and Charles Proteus Steinmetz - and devour that stuff for a while. That's practically guaranteed to get your mind running in all sorts of interesting new directions.
