Something blue-collar-ish, like cleaning, plumbing, construction, repairs. Anything 'trade'. People are significantly less self-sufficient nowadays, and setting up a plumbing business (in my country, The Netherlands) would easily get me a million-euro business without too much effort. If it has to be in tech, I would jump on the latest trend and try to squeeze it quickly before moving on.

#23Specifically though, I have struggled with the fact that many "third places" in my city are breweries - there isn't anywhere to go if you want a large, well maintained outdoor space with seating areas, that also has food and drink options, but that isn't a restaurant looking to turn over tables.
A good NA brewing space could provide the casual "come hang out with your friends/kids" third place that a good brewery does, while catering to those looking to reduce alcohol intake or those that don't drink.

#24I'd pick a SaaS category with plenty of existing (non-VC) incumbents, and build something better that I personally have experience with using, just as I did in 2021.
I’m working on something which I think would be a great product but a direct competitor got $25 million in VC funding in 2021.

#25Making systolic array chips (my BitGrid design) to bring provably secure Petaflops to the masses. They're handy for any algorithm that can tolerate extreme pipelining, including deep nets. Because everything is trivial to reason about, there's nowhere for bugs, or zero day exploits, to hide. Oh.. and we'd do an open source data diode product as well.
Do you have any other examples where systolic arrays are suitable other than matrix multiplication? As far as I am aware, other problems require different systolic architectures. So I am curious whether you are talking about a general purpose architecture.
I'm stuck in analysis paralysis... or I'd have more than an emulator[2] to show you. In theory, you can take any expression that can be broken down to a directed graph of binary logical expressions, and compile it into the "program" for the BitGrid. Because the grid is homogeneous, you can shift or rotate, or flip it to move the I/O around. The aforementioned dependency tracing makes it possible to prove the functionality conforms to the desired logical expression graph.
I need a kick in the pants to get the rest of this thing figured out. As near as I can tell, the only problems are my own writers block.

#27I have a feeling I would do something non-tech, I have a few ideas for FMCG items but I am not sure how to produce those at scale cause well its not my area of expertise, nor do I know about supply chain stuff. In terms of working capital, I don't have enough to produce it in meaningful numbers.

#28The economy is bad, everything is expensive, and there is absolutely no social climate for emigrating within EU. That would be scenario equal to having my country invaded, or getting cancer, so death rather than thinking about opening a business. AI is only a topic in huge enterprises, I have yet to see anyone starting from zero and earning any money with it. There is lots of money incoming to real estate, physical g…
Good time to find people to hire and work hard to prepare for better times.

#29If I'm feeling conservative, I would open a self-storage facility. If I'm feeling energetic and risky, I would evaluate the commercial viability of radioisotope batteries.
