> LispWorks and Franz are still alive.

Yes, but what makes us believe they won't go the same faith as all the others?

> fear what you propose would kill them very quick

Why? Is their technology that bad? I don't think so. I think they need to let people use their stuff, show to the masses the good things about Lisp and their tools and let the masses learn how to use those tools.

> If someone sees a business, they could easily layer something on top of SBCL or provided other improvements.

It is not just. Layering something on top is a lot of work :). It is software, everything is possible, but who has the manpower and time? However people do layer stuff on top. We do see people making cool and interesting stuff, but it is relatively few enlightened persons. We don't see a mass movement; perhaps masses need to see a "killer app" or something, like when JavaScript got Chrome and went from verbotten on every computer to No. 1 language (more or less)?

I think the business is made by giving the technology to people, and letting them use it. Once it is in use by individuals and people realize the power of their tools, I believe it will see more use in businesses too. As I said; I think it is a "vicious circle" as they say here in Sweden.

> Once they were gone it was difficult to keep it ported to new platforms and to fix hairy bugs.

Yes, that is a normal thing. Once the experts are gone, the platform is dead. To survive, a platform needs to attract new people and bring them up to expertise level. But every platform also has to adapt and as well to be well documented. I wish to make an extension for sbcl, I don't see any writing anywhere on how to proceed, so I have to look through the source code. It is not impossible, but is more tedious than it perhaps should be. The best thing with Emacs is actually the documentation, and the openness. I think. I don't know for sure, but it seems so.

> The specialized niche languages tend to have capable implementations with large price tags. See for example the commercial Smalltalk implementations of Cincom or SICStus Prolog

Anyone still using Smalltalk? :) Yes, of course, I agree. What you describe is how the business was done, but I don't think the history speaks in that favor. I don't know, all this are just my speculations of course, but I think that is an obsolete view on the business. It seems that all those specialized companies that target big biz are sooner or later out of that biz. What would it mean for Franz to loose Boeing? Probably quite a lot. I don't know. I am not sure Oracle is doing that great as they did in the past either. There is a lot of inertia too; big customers can't easily switch. I mean, Cobol is still there, but it does not mean Cobol as a platform is doing well.

> Other financing models tend to be fragile... or depend on other sources

I didn't mean they should switch to some other form of making business and financing. I just mean they should let their tools go free for the masses, for people making open source code for non-commercial use. For businesses they should still sell and charge of course. I don't know, perhaps I am wrong; but which hobbyist like me will pay LW 400€ for the basic license? Or whatever is the price now. They wont make money out of hobbyists, students, indie devs and alike, so they can as well let those people use the thing for free for non-commercial and open source use like other companies do. Perhaps if they have good tooling, gui builders and so on, people will use it to create some interesting stuff, more people would learn how to use their software, and that I mean would play in their favor in the long run.

By the way, to mention is that Microsoft, Oracle, Apple, Google gives away their tooling basically for free, because they have realized that they want people to learn and use their tools. I don't know, perhaps there is not money in traditional tooling like GUI builders at all in the world of web technologies.

Don't get me wrong, I don't wish them anything bad, but I think that the Lisp community is so small and fragile, and it would perhaps help with the better tools. I think is a shame because it is a nice language for rapid prototyping and development with lots of potential that the humanity perhaps is slowly loosing; but now I am perhaps bit too dramatic and cheesy :).
